Okay, simply question which is the better case? In terms of: 1. Noise 2. Cooling 3. Design & build quality 4. Features I presently use a Fractional Design R2 case which I intend to use in building a media PC. So the new case shall be used for my primary PC (gaming and everything else). Is the 500r any better than the 400r (cheaper)? My system: Asrock Z68 Extreme IV motherboard i5 2500K 8GB RAM GTX 670 Samsung 256GB SSD Seagate 500GB Seagate 2TB HP LP2475w monitor Thanks.
