Definitely not as fancy as what some of y'all have. But everything except the middle monitor and my tower PC I was given for free/basically free. I've been piecing it together over the course of a couple years.
The iMac on the left is set up as basically just an administration/monitoring console for my 2 servers (not shown). And the router on the wall is running OpenWRT as a wireless bridge to supply internet to the iMac (since getting apple wireless drivers working on Linux can be kind of a PITA lol)
PC Specs:
CPU: i9-12900k
GPU: RTX 4070
RAM: 32gb DDR5-6000
Things I was given/aquired *very cheap*:
Desk, chair (not shown, but pretty crappy lol), right monitor, top monitor (old TV), iMac (w/ keyboard), mic, headphones, audio interface, webcam, ps4 controller, router.
Edit: it's also not visible in the picture but I have a UPS under the desk I was given for free, just had to replace the batteries.
