What To Look For When Buying a Computer Case
 

Long gone are the days of dull beige rectangles. Nowadays, computer cases come in various shapes, sizes, colors, and designs and with much better features than ever before. We'll show you what to look for when buying a new computer case.

Doesn't mention the most important case buyer rule: 120s only

that's not true; ANY case fan in rear will do. bigger is better, but not a requirement in my humble opinion

It is, because the 120mm fan size allows qiuet to silent operation with 800-1200 RPM and still moves sufficent air.

it's adviced, not required :)

e.g.: for Prescott PC, rear exhaust fan (min 80mm) is required

people who went 120 don't went back to less :)

I'm about to install my Opteron system into Antec Lanboy (rear 80mm fan's ;))
