Hello !
First off, what is you budget ? There's a big difference between a 40$ aluminum case and a 200$ gaming case.
Do you want a mid-tower case or a full-tower ?
What will be your motherboard's size (so we know for sure it will fit in your case) : ATX, E-ATX, Micro-ATX ?
Is noise a factor ? Because the thicker the case, the less noise filters out. The more airy it is, the more noise come out.
Is weight a factor ?
Once I have this information, I'll start shopping for a case that fits your needs.
I can already tell you that I own a Cooler Master HAF X and am very happy with the purchase. There's lots of room and removable dust filters. However, it's very heavy and can be loud if you've got a lot of fans running at full speed and no fan controller.
