I have one spare server with two 5970s running Ubuntu 10.10. The server is located in my own company's comms room, backed up with a generator and UPS (for automatic failover to the genie power). My company provides security services so 24/7 broadband and power is crucial, so as long as my DSL connection is okay you are ok as well (and it is a top package business connection, so very seldom goes down, if ever). I offer a full server root access, you can do whatever you like (however, this is a DSL connection, so wouldn't be suitable for a busy webserver).
The server comes with all drivers installed and also m0mchil's miner, fully tested and ready to go. If you need any more info let me know.
