I don't know how hot your computer room gets.
In my home office there is a 2k VA Tripplite UPS, 4 tower PC's, 2 of
which run 24x7 along with ham radio gear that runs all the time and big
old 20 amp dc power supplies to run the ham gear. Add to that 3 CRT
style displays a laptop computer, battery chargers, printer, 2 routers,
a switch, a couple of police scanners, and a small Merlin PBX. Room size
is 9 x 15.
A/C in room next to it but no A/C duct in this room. A ceiling fan in
the computer / office seems to keep the air mixed up enough to be
comfortable even when it is 98 degrees outside.
