I wouldn't advise it. I doubt they were designed with such modification
in mind. Safety should come first with expensive server-grade hardware,
which is why the fans run as fast and noisy as they do. Such hardware is
designed for data centers, where noise is the norm. I wouldn't advise
placing one in a home environment to begin with unless you are prepared
to deal with the cooling and noise associated with rack-mounted server
hardware like that. I admit I've been tempted in the past to install
rack-mounted systems in my home, but wouldn't dream of doing it without
specifically designing a closet/room for the additional cooling and
noise insulation required. For my needs, a Mac mini closet server and
Mac Pro workstation provide the server / data crunching ability quite
sufficiently for a home environment, without all the headaches of a rack
setup.
