Case recommendation needed (almost done!)

Here are the components:
MB = ASUS P5Q-E
CPU = Intel Q9550
CPU HSF = ARCTIC COOLING Freezer 7 Pro 92mm
GPU = 2 Sapphire 100237L Radeon HD 3650's
Mem = 2x2GB DDR2-800 Mushkin
HD = 2 x WD 640gb hard drives
PSU = CORSAIR 550VX
OTHER = TEAC Floppy drive; Possibly 1 internal DVD-RW

Usage:
-No games or OC'ing
-Home video editing
-Trade for a living across 3 LCD's
-Basic web/email/etc.

I don't plan on changing much around once I get it all together, it should last me at least around 5 years without much changes (maybe down the road I'd add 1 more Hard drive or something). I don't need an overkill case, just relatively quiet if possible, relatively cool (temp.), and able to fit all the above comfortably w/ cable ties & stuff. See-through side panel would be a plus, but no biggie.

I heard the CoolerMaster 690 w/ stock fans is a good mid-range tower, so I guess that's my basis for comparison...

Also, do I need to purchase/add dust filters for the intake fans? How?

Tnx Paul. That takes care of my Antec 300 vs. CM690 decision.

I think now it all boils down to:
CM690 vs. CM Centurion 5 CAC-T05-WW

The one thing about the 690 that I don't like is the ports are on the top of the case which makes it difficult for me to plug things in since it sits under my desk...

Any pro's/con's for the Centurion instead of the 690? Would it do the job for me just as well?
