lol...unless you're rich i wouldn't spill that much money on cases...
the quailty difference between a good $100 and the $200 case arent that big. what you're paying for really is design and looks (which are important too). and some other little stuff. but $200 is a little extreme, unless you have the money.
though i recommend a well built case, i went for some cheap nice looking one i found at pricewatch for $30. quality wise...it's a POS. made the set up a big hassle. but once i am done, i dont care for it...it's not like i am going to kick it to see how well built it is. but the best part is, it looks really nice...like a $100 case, but only for $30.
anyways, cheap cases will do. just find one that suits your flavor. sometimes having an ugly case is worse than a crappy built one cause looking at it doesn't make you proud at all.
