Fixed Computer, What Now?

Hey guys I have two Linux computers, a raspberry pi and an old E machine I found. I am looking for a realy good idea of what to do with them.

Raspberry Pi: Make a smart TV. There's plenty of decent software out there, get a wireless keyboard and mouse and now you've got a machine for Netflix and content consumption on the TV. Set it up to emulate games or something.

The E Machine might work as a file server. You could keep things like movies and music on it, then configure them to be accessed by other machines in your house (like the Raspberry Pi Smart TV). Also if you've got only a few friends and a decent upload speed, dedicated servers don't need a lot for around 5 or 6 people. I had a pretty amazing Minecraft server for like 10 people running off of an old Dell for the longest time.
