Good cases cost money, but in the long run they are cheaper.
Before you buy a case ask yourself - what part of the system will most likely stay around for several upgrade cycles? The most likely answer - the case. So why cheap out? You get what you pay for. I've had mine for going on two years which is an eternity for any part in my house. I still like it, lots of room, runs cool, it's quiet, and it's expandable.
Talk to Jim Hanson @ CoolCases he carries some of the best cases around. The best part is Jim will work with you to determine which case best suits your needs.
(Though I still think the pop-top mod on the Chenbro Genie should be called the "Ej-top" )
