Do P4's still require a special case and/or mobo to mount their HSF? I've got an Antec case that I bought in September '01 (I can't find the model number on it...it's all painted. there are three (3) 5.25" bays, a single floppy drive, and 3 internal drive bays). I'm wondering if it will be able to support it. I'm planning on buying the Asus P4P800 mobo.
