This is my vGPU server powered by Proxmox. Basically multiple private cloud gaming PCs in one machine. Powered by a AMD Ryzen 9 3950X that I got "for parts with bent pins" on eBay for a great price ($135USD) in an Asrock X570S PG mobo. When I ordered the mobo I initially got it for it's fanless chipset cooling but it ended up having the perfect PCIe slot layout for my needs. All in a Fractal Define R3, as I have multiple R3-R6 cases to chose from & the R3 I feel has the best sound dampening. Using a Corsair RM650i as it's all the power I need & it gives enterprise server like features as the Corsair PSUs are natively supported in Linux. Using a software package called "CoolerControl" which let's me control fan speeds based upon custom fan profiles/settings. So the passively cooled Tesla P4 can be cooled with a 40mm (15K max RPM) fan & have it fully controlled based upon that card's GPU temp. The Quadro RTX 5000 I got for a great price & let's the system support Ray Tracing based titles. The Tesla P4 is split into 775MB based VMs as the profile's resolution is limited to 1280x1024 & used to play early-mid 2000s based games so plenty of VRAM for those titles. I'm using mostly Parsec to remote in but I also run Sunshine/Moonlight as a backup method along with AnyDesk. I wanted a "NAS" that's always available to these VMs so I put in an Icydock 3x 3.5" Hotswap cage & use Samsung 860 Evo 1TB drives in a RAID5 so about 1.8TB of usable space. Went with Samsung drives as they show the remaining life directly in the Proxmox UI so I don't have to login via SSH & manually check them regularly. Even under a load of 6x concurrent users the system stays pretty quiet which is pretty nice for what's it doing.
