How would you build a GPU-heavy node? (poptalk.scrubbles.tech)

Simple as that, I have a few GPUs hanging around and I want to build a GPU node for my kubernetes cluster. I already have one, GPUs are attached and it can do cool things like transcoding plex easy enough, but I'm starting to look to the horizon for my next big projects.

So, dream machine, how could I accomplish building a big ol' server with the GPUs I have hanging around and maybe a new one?

What CPU/Mobo, and maybe most important, power supply, would you recommend for running maybe even 4x GPUs? Or maybe just 3 and I'm being crazy.

Won't be building tomorrow like I said, but I just thought of this and was like "man, I bet not a lot of consumer hardware would support this..."

I wonder if you could copy (or buy used) some crypto mining rigs for this. I'm not sure if there's some kind of bottleneck im not aware of though.

That's what I was thinking, but less... Fire hazard? I've seen some of those that are just crazy. Idk mostly need a board that can handle it. Idk just dreaming of a new project with spare stuff hanging around.

I would guess they're a fire hazard because of the overclocking they do. They're either a long term (heh) project and they're immaculate, or they know they need to squeeze every bit of value and abuse the fuck out of those GPUs. I think you can tell if a rig is dangerous so you should be ok

Yeah I watched some of those and they were just nuts, just wires running everywhere, PSUs hacked so they can have multiple PSUs on a single node, paper clips - just stupid.

Often the mining rigs use just 1-4 pcie lanes (per GPU), because more isn't required for mining and it saves on other costs
