There are other brands/sizes of those trayless hotswap enclosures too.  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.
