Yeah, the rack was just to store the servers better. We're actually not using the cooling fan at all -- our basement is naturally a good temperature all year round, and hasn't changed at all with that equipment.
The top server doesn't have the right rails, and is not properly inserted. The cabling job is a *lot* nicer than it was :).
Yeah, that keyboard is just some one I had laying around. Actually I think it might have been from a Gateway 2000 pc the previous owner of our house left here when they moved out, which I am now using as a Smoothwall router.
