Hey everyone. Thanks for all your replies.
I ended up implementing quite a few of the suggestions.
Managed to get an old dell with a i5 8500, 16GB Ram, 256GB Nvme, and a 1TB Hdd for £120 which I think was a decent price. It's been rock solid for me and my friends game servers and going to set up jellyfin next.
Been really enjoying tinkering with is, experimenting with unraid might switch when my free trial ends.
Thanks again.
