Find a cheap low power CPU to swap in. Or tune it in BIOS to use less power (some CPUs have an eco mode that make this easy).

Sell the gaming GPU and put in something that does video out, or use a CPU with an iGPU.

Big gaming cases with quiet fans are quiet.

Selling the GPU and tuning or swapping the CPU can put money in your pocket to pay for storage.

It is water-cooled and whisper quiet aside from the GPU fans. So yes there are options.. but right now selling the RAM alone might pay for a whole mini-server. I'm going to try to sell it locally to a PC gamer though, get some proper use out of it!

Server boards (like with xeons) won't have eco modes and will not be made for such use case. Nor server cpus. Idle servers are wasted money, so they are not designed for such use cases.

Big case also means big space.

This is literally impossible with most server grade stuff. It’ll never be as efficient as the low power modern stuff.
