The nice thing with using smaller hardware that is also super quiet is that you can just leave it on your desk - in this case the machine is on a secondary input to one of my monitors - a Dell that also has a built in USB switch, so changing the monitor input over also moves my keyboard and mouse over! I'd go for a server motherboard if the machine was remote though - eg if it was going to sit in a cupboard, basement, etc. Remote media with a decent IPMI is a godsend for that.
