How about some basic parameters???
Overall size: Really Big, Large, Mid, Compact?
Drive space: 5"ext, 3" ext, 3" internal?
Mobo size: Full, mATX?
Mobo chipset/CPU?
How many add-on card slots do you need now and might you need in the future
There, that should help narrow it down, but generically I haven't seen anything much crisper in a no-frills, average size case than the new Athenatech 503 series recently.
