My ATC201 performs flawlessly. It cools great with its 2 intakes and 2 exhaust fans and is great for overclocking. It also has a dust filter covering the intakes that you can take out with a socket screwdriver and a philips. All the case screws are thumbscrews including the expansion slots and the four bays are occupied perfectly with my dvdrom, cdrw, newq plat, live drive ir. However, my only little complaint would be the non-ball bearing fans that come stock with it.
