Repurposing old gaming PC for first homelab

I’ve been aware of homelabbing for a while and have previously hosted a few game servers, but I’m looking to get more serious about it.

I recently upgraded my main PC and now have my old system available. I want to repurpose it as a dedicated homelab.

SPECS

cpu: 10700f

gpu: 1660S

ram: 32 gigs ddr4

storage: 500gb ssd

I am mainly interested in running game servers and a media server. Still open to experimenting and learning more.

Any recommendations are appreciate.

I also have about 100 dollars if I need to buy anything to run it.
