I have a server running in my basement with 2 nvidia Tesla GPUs that I bought for ~$70 each on ebay. (Unfortunately the RAM cost an arm and a leg). I built it for inference, but I also set it up to run sunshine server and now I have my Steam library on the TV through a Raspberry Pi 3. Even better, it was a fun and interesting project, maybe not as straightforward as you think. Unfortunately it's entirely possible that it costs .24/hr just for the electricity.

Now, this feels fine with <10ms input latency over wifi. Even in 2026 I'm skeptical about sending my input to Atlanta and back.
