I got my hands on a free HP Proliant MicroServer.

It's got a pair of 2TB hard drives in it (I don't care what's on them), and no disc drive or anything. I have a MacBook Pro, a spare monitor, USB keyboard/trackpad combo thing, some various random cables, and a bunch of video files it would be cool to have easily accessible (but not on my laptop). What can I do with this thing? Where should I look/ask for more info?
