After relating a EFH I had made up my mind that IT be housed in a 19 "rack in the basement, instead, as explained earlier in an apartment, in my study. In addition I have also bought a current 2U server, which to me, however, even for a cellar was too much too loud. In order to experiment with the ventilation (due to the use of L version for both E5 Xeon CPUs this is possible), the original built by Intel decoupling fasteners for the system fans were not suitable. These sold by Noctua accessory are ideal. First, they sit firmly in the plate, and secondly, they may also be in close to each other fortified fans use easily, since they protrude fan side through the holes on both sides at least 25 mm thick fans.
