Building a Cache server?

So, with Unity announcing the team licence is now free as part of the Pro package I already own, I’ve decided to build a Cache server using Linux. I’ve read that ram is very important but I’m also wondering about which version of linux and hardware is recommended. I’ve never used linux aside from installing Ubuntu years ago and having a little play around, so any suggestions would be great.

Thanks

Anyone?

Anyone from Unity? Before I waste cash?

I use Cache server on Windows here. Works OK.

You can install it on your own machine. It works well on that too.
