Could you tell me the difference between a "Home Theater" case and a "Rack Mount" Case? The computer I'm building will sit on my desktop and I'd like to stack my stereo components on top of it (Reciever, turntable, tape deck). I was looking at the Thermaltake Tenor but was wondering if you had any better recommendations. I will need 3 5.25" drive bays and 2 3.5" drive bays on the outside.
