I live in a dorm room and keep an R610 about three meters from my bed. You can use some magical IPMI commands to disable the internal fan feedback loop and replace it with a custom one (usually the defaults cool the server to around 30C, which is not really necessary). This makes the server more quiet then the small fridge I also have in the room. The 100W power consumption definitely makes the room warmer. It is approximately like having another person present.
