Modern PC in a funky retro OEM case from 20 years ago.
It's… well, kind of a mess inside, and there's significant cooling limitations that mean I can't really overclock it. But it works, and it looks cool from the outside.
(I… don't actually have Windows 95 on here, the second picture was faked with a virtual machine. Real OS config is dual-boot Windows 10 & Linux)
Note that I made a poor choice of RAM; these modules won't reliably clock over 2400MT/s on my Ryzen board.
