So i have a older dell OptiPlex laying around running a i3 and 8gb of ddr3 ram. Now I've been wanting to use it for something for a while but couldn't think of anything as my main pc is the powerhouse computer, I have plenty of storage on here so i don't think a server would be practical, at least to my knowledge. I can have it hardwired and on all the time as i have extra room, maybe use it as a Minecraft server of some kind? Any ideas are greatly appreciated.
