The trayless hotswap enclosures that others have suggested that fit in 
the space where 5" drives would go generally have their own cooling 
fans. I've used a unit from Startech and swapped one of the drives out 
of a raid weekly for an off-site rotation without any trouble for over a 
year now.  You do need a big tower case that could take 5" drives all 
the way down, but it's nicer than having cables and power off to an 
odd-sized external box and very handy to not have to open the case to 
trade drives once it is set up.  If this is a single-user PC or even a 
media server for a few people at once you probably don't have to worry 
about extreme speed issues and would get along fine with an
8-port PCI-X or -E card.
