I personally do not consider these tower machines put sideways rackmount
servers. Such tower machine is usually not designed to works in the server
room (where cost per square foot of floor space per Month is
consideration), a bunch of machines like that can be replaced by single
real rackmount server, the last usually would be much more robust and
durable as they are designed to work more stressed. Of course, server room
full of tower machines would be quieter, but that one I would rather
describe as room full of servers instead of server room (should use the
word desktops or workstations not servers for the former).

I should have added "rant" tags... I have mild excuse though: I do have my
share of trouble from these put on the side towers (chosen by somebody
else) in my server room.
