Pictures below build specs, Rack size 16" x 20" x 18" (H x W x D) 4.5" higher with wheels

Purchased 2020 during the pandamic with the CPU/PSU/GPU shortage. Couldn't get a 3080 ti, 5900X, or the PSU i wanted. However I proceeded with the build and it turned out great. the best part is its portability, with wheels i can move it, an all encompassing enclouse to house my computer, all my networking equipment, media equipment and backup solutions. On the ToDo list is a Capture card for the PayTV and Nintendo Switch, so I can output it on the computer, right now they are going through a 32" TV.
