I have my home server in the attic, a 4U with a bunch of drives in it running ZFS. 4G RAM, Q6600 Intel chip - I've been running the same hardware for years. The fan sound is unnoticeable - it's on the other side of the insulation, and it's approximately located above my desk in my home office. It gets hot in the attic in summer, but I've had no failures thus far (no hardware errors from overheating, no drives died). Dust filters on the fans need cleaning off every year or so. I'm due to upgrade it, 4G ceiling is starting to get tight when using more recent software.
