My Computer Headquarters/Office

In November of 2019, I upgraded my computer(s). I replaced a late 2013 iMac with a 27-inch montior with a new 27-inch iMac (5k monitor). This new all-in-one computer has the exact same desk-space profile as the previous iMac. I switched from a Mac Pro to the iMac line in 2013. They take up considerably less space, costs a lot less, and this modern line of iMac has more processor power than my old Mac Pro (early 2009 model). The new iMac (purchased in 2019) has an amazing 5K monitor. After my secondary Dell 30" monitor died (after 12+ years of service), I replaced it with an LG 27" monitor, so I've got two monitors (stacked vertically as shown here).

The computer upgrade was started at the begining of November and completed by the middle of November, 2019. Kim and I planned and saved for more than five years in preparation for this upgrade. With a budget of appx $5,000.00 (I didn't spend all of that), I initially planned the computer upgrade for November of 2018, but Apple didn't release an adequate iMac model that year. I considered the purchase of a Mac Mini as a replacement to the iMac desktop, but the Mac Mini doesn't come with a monitor (I didn't want to step down on the monitor option), so I would have had to purchase a monitor separately, and then I would have two 'extra' monitors if I went back to the iMac model the next time I upgraded. Instead I opted to wait.

I purchased this IBM powered iMac just before Apple's switchover to the M1 architecture (The new Apple designed/engineered CPUs). Thankfully, I managed to acquire a 27 inch iMac before they were discontinued. Since my purchase in November of 2019, Apple has seemingly abandoned this form factor. The 27 inch iMac is a perfect form factor for my needs, but Apple still hasn't (as of Jun 2022) returned this type of desktop to their line up. As a matter of fact, with the introduction of the 24 inch iMac (an M1 design), the new Mac Studio form factor and the reintroduction of the Studio Display, it seems that this may be the last of the 27 inch iMac line...

Now that I'm not in the military anymore (I wasn't making much money in the military (military members make considerably more now)). With my new career, I can finally afford some of the nicer toys offered to consumers these days. The previous computer (another iMac) was purchased in November of 2013. It lasted a long time, and it did it's job well. With the purchase of our new computer (in 2019), I sold the old one back to Apple (as a 'trade-in').

My Computer: Purchased 01 Nov 2019

Hardware/Primary Desktop machine:

Machine type: iMac (Retina 5K, 27-inch, 2019/Model Number A2115/Model Identifier iMac 19,1). This is my second iMac. I chose the iMac all-in-one desktop model instead of the Mac Pro (back in 2013). In comparisons of computing power for my needs, I now find that the iMac line has sufficient power to handle my computing needs. You no longer need a Mac Pro to do video editing, rendering, production (even the home video type). In the past, the iMac line couldn't adequately handle this type of application (in my opinion). Since occassional video production is now my most CPU/Graphics intensive application, I easily switched over to the iMac line for my computing needs.

CPU Type: 64 bit, 14nm, ninth generation Intel Processor (released in October of 2018), code named 'Coffee Lake'.

CPU Speed/Number of Cores: I selected the standard build CPU category. The base option comes with a 3.7GHz 6-core Intel Core i5 processor. With the Turbo Boost (automatically enabled based upon processor load), this CPU can clock up to 4.6GHz. This CPU has six, direct channel processing cores (no 'Hyper Threading'). The 6 core CPU has a 9MB shared L3 cache.

Memory: The base model comes equipped with 8GB (2x4GB - Two slots unoccupied) of 2666MHz PC4-21300 DDR4 SO-DIMM SDRAM (260-pin) - The machine has 4 memory slots. Once again, I exercised the 'Bigger is Better' maxim. I didn't quite max out the RAM, but I did opt for a juicier option than the default. I upgraded from the 8GB option to a 32GB option for $540.00. Normally, I opt for a second party upgrade (installing it myself). I'm not sure why I didn't do that this time around... I really should have. Apple charges way too much for the RAM - I could have installed 64GB of memory for appx $400.00 - I'm such an idiot! ...Perhaps I'll attempt an upgrade to 64GB by purchasing some second party RAM? There is some risk that the RAM from two different sources may not work in the iMac. Mismatched RAM is a thing. It could happen.

Display: The iMac desktop comes with a 'built in' monitor - Actually, it's probably more accurate to say that the iMac monitor comes with a 'built in' processor. This particular iMac comes with the juciest monitor one could ever want! It's an amazing 5K monitor. With a 5120 x 2880 resolution, you can clearly see the wrinkles on a gnats ass with this monitor (I operate the monitor using a 2560x1600 resoltion). The glossy glass-covered widescreen monitor has a 16:9 aspect ration, LED backlighting, featuring IPS (In-Plane-Switching) technology, and a P3 color gamut (P3, aka PCI-P3, is a common RGB color space standard created by Apple, Inc) and 500 nits of brightness (the Nit is the standard unit of luminance used to describe various sources of light. A higher rating means a brighter display. Ratings of 500 nits or more are extremely good).

Hard drives: With only one slot for internal storage, I'll need to connect external drives via USB and/or Thunderbolt in order to get the same kind of redundancy/storage I had on the old Mac Pro. The old Mac Pro had a total storage capacity (counting internal and external storage) of 9.28TB.

Internal to 27" iMac:

• This model came with a 2TB fusion drive. The fusion drive is a serial ATA spinning hard drive (7200rpm) paired with (via PCI-e) a 128GB SSD drive for optimal speed. The 2TB drive is more than spacious enough for my current needs, and the SSD addition makes for super snappy apps, especially those I use most frequently.

External/Network drives:

• External/Network drives:
• G-Technology G-RAID 4TB hard drive (Model number GRATHNB40002BAB SKU 0G02289). This 4TB device contains two Hitachi hard drives (2TB each). The drive is a Thunderbolt 2 device (connected to USB-C Thunderbolt 3 port using a Thunderbolt to USB-C adapter), which I have externally connected to my iMac to serve as a primary backup for my system level 'Clone'. This bootable clone is maintained using Carbon Copy Cloner software by Bombich.com. In addition to the 1TB partition for system level backup, I've configured another partition for external storage, Archive03 (1TB). While this hardware storage device can be configured as a RAID device (and it originally was), I am using it as two separate 2TB devices.
• Buffalo Technology 6TB hard drive (HD-LX6.0TU3). This massive hard drive is attached to my network by way of my primary router. I've configured it to serve as a primary back-up destination (Archive01 (2TB - Set up as backup for music, movies and photos), Archive02 (2TB)), and a Time Machine backup destination (TimeMachine01 (1TB), TimeMachine02 (1TB)).
• Seagate Expansion 8TB Desktop External Hard Drive USB 3.0 (STEB8000100)
  • One of these bad boys (8TB hard drives) is used as my 'Media Drive' - That's right, all my media (music, movies, photos) is stored on one of these hard drives. Seagate isn't a very reliable brand, so I bought a 'replacement' warranty when I purchased these 8TB drives. The warranty was inexpensive, but it's a full replacement warranty with a content backup clause. So even if the drives fail, I'll get a new drive with my data copied to the replacement.
• Seagate Expansion 8TB Desktop External Hard Drive USB 3.0 (STEB8000100)
  • No that's not a typo, I bought two of these! While I've got all my media on one drive, I'm backing up that drive to another 8TB (backup for all my media). As noted above, I'm not very confident with the Seagate brand, so I bought a 'replacement' warranty. Having one drive as a back-up to the other pretty much guarantees the security of my data. Unless my house burns down... That's a sad thought. I sure hope that never happens!
• Synology DiskStation 2-Bay Network Attached (NAS) DS214: w/2x WD Red 2TB NAS Hard Drives - 5400 RPM Class, SATA III 6Gb/s, 64MB Cache, 3.5" WD20EFRX - My NAS drives are configured as RAID1 devices. I'm storing backups of data on one of these devices and using the other for remote access to some gaming materials.
• Synology DiskStation 2-Bay Network Attached (NAS) DS216: w/2x WD Red 2TB NAS Hard Drives - 5400 RPM Class, SATA III 6Gb/s, 64MB Cache, 3.5" WD20EFRX- My NAS drives are configured as RAID1 devices. I'm storing backups of data on one of these devices and using the other for remote access to some gaming materials.
• Buffalo MiniStation 500 GB USB 3.0 Portable Hard Drive (HD-PCF500U3B): A portable hard drive connected directly to my iMac. Just in case I ever need a portable solution with more capacity than a thumb drive (I've got plenty of those handy). Buffalo is a brand that I trust/know, and this drive fills a niche case.

Total storage = 34.5TB

Media Drives: Apple stopped including built-in media drives (optical drives) back in 2008. In January of that year they introduced a new MacBook Air that didn't have a CD/DVD drive. That was the start of their efforts to eliminate these media drives completely. As processor became more powerful (faster), internet speeds increased, and drive storage became cheaper, Apple realized that media drives were no longer a necessary component for modern computers. Over the next eight years, Apple continued to remove optical drives from it's computers. The last Mac sold (in Apple stores/online) with an optical/media drive was the mid 2012, 13", second-generation, non-Retina (display technology), MacBook Pro (MacBookPro9,2/Models MD101xx/A, MD102xx/A). I've been using external media drives since November of 2013, when I purchased my first external SuperDrive in preparation for my first iMac (purchased in November of 2013).

• Apple USB SuperDrive: The iMac (the one I purchased in 2019) doesn't come with any media drives (CD or DVD). I purchased a USB SuperDrive (back in 2013) for any disk reading/writing needs. Model MD564ZM/A is a slot-loading 8x SuperDrive (DVDA±R DL (double-layer)/DVDA±RW/CD-RW). Writes DVD+R DL and DVD-R DL discs at up to 6x speed. Writes DVD-R and DVD+R discs at up to 8x speedWrites DVD-RW discs at up to 6x speed and DVD+RW discs at up to 8x speed. Reads DVDs at up to 8x speed. Writes CD-R discs atup to 24x speed. Writes CD-RW discs at up to 16xspeed. Reads CDs at up to 24x speed.
• SEA Tech Aluminum external USB Blu-Ray writer Super Drive. One external drive is not enough. I needed a Blu-Ray reader, but wouldn't be content unless I could also write to Blu-Ray discs, just in case. I purchased this drive from Amazon. On the back is a label which indicates that this is a 'Archgon' Ultra Slim Optical Drive Model: MD-8107-U3. Apparently it has a Panasonic Blu-Ray device inside. According to documentation I was able to find online, this drive is able to read and write to the following formats: CD, DVD and Blu-Ray. It can read UHD 4K BD, but it can't write to the UHD Blu-Ray discs. I use it to read Blu-Ray discs.

Internet connection: I unse Xfinity/Comcast as my Internet Service Provider. There are other options in my area (broadband wireless, ADSL over phone lines, Satellite), but they can't possibly provide the speed afforded at the price that Comcast offers. My connection speeds: 100Mbps (download) / 5Mbps (upload) always-on cable (Motorola SurfBoard SB6141 DOCSIS 3.0 cable modem) internet connection (Comcast) w/DHCP IP assignment (Plan was last upgraded on the 15th of Mar, 2020. Cost (after a one year promo period) is ~$55.00/mo). I own my own modem, my own router, and would switch to a different provider if I could find one that provides comparable (or better) speeds for the same (or better) price. Xfinity hasn't been reliable, and their customer service is abysmal.

Wired/Wireless Network: Setting up and maintaining a proper wireless network is no easy chore. Especially when you have a large house and a lot of devices employing several different wireless standards for communications. Add in some wif-fi wielding neighbors in a standard tract-home community, and you've got one challenging wi-fi landscape.

• My primary router is now an AmplifiHD mesh router. I have configured the router to produce a mesh network using two Amplifi mesh point extenders (purchased separately, otherwise the endpoints are hard coded/only compatible with the AmplifiHD mesh router sold with them in the 'bundle'). This router is capable of multi-hop transitions across the area of coverage (no need to re-select/re-authenticate as you move from one device's coverage area to another), self-healing wireless coverage and enhanced range (the benefits of mesh routers). The router's mobile app (for iPhone/iPad) is intuitive and easy to use. The web based configuration capability is just about useless. With the mesh point extenders, it's easily capable of covering my 2,200sqft house (ranch style) - plus (the previous router left me unable to connect while mowing the lawn). Thankfully, the router (it's manufacturer) notifies me when there are updates available.
  • Legacy: Unfortunately, Apple has stopped producing their Airport line of network devices. Apple officially discontinued the AirPort product line on the 26th of April, 2018. They've sold off their inventory, and they no longer sell the products through their online or retail stores. It's a sad day. Apple made some great network devices. They were innovative, reliable and well supported. Unfortunately, I've had to turn to someone else to provide my network needs. I still own some of the Apple network devices, but they no longer serve in a primary boundary role (Internet/Intranet interface)
• Secondary router/running in bridged mode: One of Apple's older MB764LL/A Airport Time Capsules. It's a 500GB model, with 802.11a/b/g/n simultaneous dual-band wi-fi capabilities. I'm using this router as a network pass-through (bridging) to provide more ethernet and USB connectivity, and it's currently generating a second set of wireless networks (1x2.4GHz, 1x5GHz and 1x 2.4GHz Guest network). Yes it's old, but it still works well. I'm using the timecapsule with my wife's laptop. 500GB is more than enough to back up her laptop.
• Secondary router/running in bridged mode: In November of 2013 I bought one of the new (at the time) ME182LL/A Airport Time Capsules. The 3TB model (~$379.00). The Time Capsule is a simultaneous dual-band (2.4GHz/5.0GHz) wi-fi base station (Apple's Airport Extreme router) with 802.11a/b/g/n/ac wireless, Bluetooth (modified in Apr 2012 to use an external antenna), an Ethernet WAN port, three Ethernet LAN ports, and one USB port. It supports the following protocols: NAT, DHCP, PPPoE, VPN Passthrough (IPSec, PPTP, and L2TP), DNS Proxy, IPv6 (6to4 and manual tunnels). There's a 3TB hard drive inside the casing for use as a Time Machine backup (I'm using this one with my iMac). Unfortunately, my plans to use this as my primary router were thwarted. It failed to perform as expected. I wrote all about that failure on my blog. No matter what was tried, I could not get the Time Capsule to create a hidden network (which is o.k. - I can live with that) or allow my Airport Express to pair with the base station. In the end, I connected the brand new Time Capsule to my network in bridging mode. I've added it to my network as a Time Machine destination, and removed it from any network/base-station responsibilities.

Video card / Displays:

Video card: iMac desktop - This particular beefed up version of the iMac comes with a Radeon Pro 580X video card with 8GB of GDDR5 memory. You need a lot of memory to drive that 5K monitor, and this beast has an awesome video card. The monitor/video card simultaneously supports full native resolution on the built-in display at 1 billion colors, and 1x 5120x2880(5K) external display (60Hz w/1 billion colors) or 2x 3840x2160(4K UHD) external displays (60Hz w/1 billion colors) or 2x 4096x2304 (4K) external displays (60Hz w/millions of colors). I currently run the primary monitor at a 2560x1440 resolution (so I don't have to squint) for routine/daily use. The video card/iMac also has support for Thunderbolt 3 digital video output via the Native DisplayPort output (to the built-in display) or the USB-C ports on the back of the built-in monitor. You can also connect Thunderbolt 2, HDMI, DVI and VGA monitors using applicable adapters. Finally, the monitor has a built in FaceTime HD camera.

Second display: Up until Jan 12 of 2022, I used a Dell 30" monitor (a DELL3007WFPHC Display) with my new iMac (as a second monitor). I used the Dell 30" monitor with three different Macs, going back to 2009 (The refurbished Dell 30" monitor was purchased 19 May, 2009 for ~$800.00). That refurbished Dell monitor lasted me more than 12 years. I'd say that I definitely got my money's worth. It cost me a bit to get the Dell 30" monitor to work with my new iMac (my 27" iMac w/5K retina monitor), but I eventually got it to work in 2560x1600 mode (by purchasing some equipment (a Club 3D CAC-1510 (USB-C) to DVI-D Dual Link Adapter for $42.49).

In January of 2022, I purchased a new second display. I purchased an LG-27UN850-W 4K HDR display (from Amazon) for $479.99. The new monitor isn't as big as the old Dell monitor (27" vs 30") and it's 16:9 aspect ration means it's wide but squat. The new monitor can display images in UHD (Ultrafine High-Definition) resolution (3840x2160), but I'm only using a 2560x1440 resolution to match my iMac's display (my eyes can't quite cope with the 3840 or 5120 that my monitors are capable of. I've also got the HDR capability turned off for default work. If I'm watching a movie, I might turn it on. Of course the new monitor is mounted in the same manner as the previous monitor; on a wall mounted articulating arm above my iMac (Thankfully I didn't have change out the mounting bracket - Thank goodness for those VESA mounting standards). Hopefully this monitor will last just as long (or longer) than the refurbished Dell.
