Was using an old Dell Optiplex 390, with i3-2120, 8GB RAM and a Crucial 256GB SSD stuffed in there along with a couple 1TB spinning rust disks for data storage, but it just wasn't enough to keep up with the fast paced environment when I began a new contract position working 100% remotely, so this build began in March of 2017. This was the end result, cobbled together over the period of 12-18+ months, beginning with the core components and adding more storage and an additional display as time went along.
Thank you for your time and attention to my little hardware related post.
EDIT [April 2019]: Previous Dell laptop died ~2 days before family vacation (about a year ago now), due to a loose connector causing video to no longer be output to the display, so I was forced to quickly pick up a BestBuy special, an HP Spectre x360 - 15-bl112dx:
- Intel i7-8550U @1.8 GHz base frequency, up to 4 GHz with Intel Turbo Boost Technology, 8 MB cache, 4 cores
- 16 GB DDR4-2133 SDRAM (2 x 8 GB)
- NVIDIA® GeForce® MX150 (2 GB GDDR5 dedicated)
- 512 GB PCIe NVMe m.2 SSD
- 15.6" diagonal 4K IPS (3840 x 2160)
[Networking details] Also added an 8+ month old attempt at a network diagram, which turned out to be a jumbled mess, but hopefully someday I'll find/make time to update it. Currently using a lovely Edgerouter 12 with our 1000/50 Mbps fiber service provider, paired with redundant Pi-holes running Unbound for my own little in-house recursive DNS server and a UAP-AC-LR that happily blankets our little home with absolutely solid wireless coverage throughout.
