windows isn’t the problem. it can and will run all day, every day.

your existing box isn’t a server. it’s a desktop pc that you’re doing ‘server things’ on. you want a server, make it one:

move the retro gaming, the ‘shitposting’, the 3d design work, and the random internet use that goes with those things, off to a different pc.

leave the existing one with the *rrs, the storage, the drivepool and snapraid… get everything else off. then leave it alone.
