Reminds me of a "datacenter" me and some house-mates built in a basement when in uni.

We stuck the servers on top of a few pallets so they wouldn't be submerged in water when it rained. The power was fed from the living room above and the network cables pushed through gaps in the floor boards to all the bedrooms. The adsl router was nailed to the wall on the top floor above the beer fridge and ran smoothwall I think it was.

We even tried running a serial link for a monitoring terminal in the living room over standard audio cable .. it kinda worked .. and was called teethanet for some reason.

Overall it worked like a charm and I don't remember there ever being downtime .. even when there was a foot of water surrounding the servers.
