A gaming opprotunity?

My wife and I just moved into a rental home and the former tenant abandoned a number of possessions in the home and the landlord said what we find is ours. He had given the prior tenant a few weeks to get these, but given partly the fact that our landlord is suing the former tenant for a generous amount of money (more then 10x the value of the left items) he never came back fro them. There were a few weeks between when this guy was evicted and when we moved in.

One of his more unique left possessions was an old Xbox in a see through blue casing (I don't know if it was a special ed or after market I've never looked into it). Thing is it only has a power supply plug, that's it (or what I'm hoping is the power supply).

How hard would it be to get a controller and ac cables for this thing? Is this stuff still readily available for semi cheap? I've seen I can get games for semi cheap. I'm seriously thinking of getting the parts for this and hooking it up as part of a man cave. I'm just wondering if it is still possible. Also am I going to need a memory card for this?

I know it sucks that this guy lost his xbox, but if I can enjoy it why not (we also found a portable DVD player with the goonies in it, and a few sealed boxes of assorted computer parts).
