NZXT Lexa Blackline Case
 

If you are looking for an affordable case with excellent air circulation, plenty on drive bays, fits an nVIDIA 8800 Video Card and has holes for an external water cooling system I would definitely recommend this product. These are the key features you should be looking for in a case and it does have that. It also has other features like a tool-less design, external ports, dust filters, cable management cage, and more. Despite all this I can't get past the looks…
