Case - no front USB which makes takes it off my build list.
Cooler - With twin GFX cards, I'd want something w/ bit more cooling
-$50 - Scythe Mugen 3
-$80 - Thermaltake Silver Arrow
MoBo - Warranty comes up short compared to industry standard 3 years but well reviewed .... good choice if it lasts.
GFX - If ya worried about the noise, consider the Asus, factory OC'd to 50MHz less but I got 7 outta 8 to 1000Mhz w/ no voltage tweaks
Using the following in this PSU calculator, I came up with 682 watts. This does NOT include overclocking the GFX cards. Settings:
High End Desktop
Intel 25o0k OC'd to 4.8GHz @ 1.41 volts
2 sticks of RAM
2 560 Ti's (not overclocked)
1 SATA HD
1 SATA DVD-RW
1 PCI-E x4 card
5 USB devices (KB, Mouse, Headphone, Mic, phone)
1 Card Reader
3 120mm LED fans (Case rear and 2 on Cooler)
2 200mm LED fans
15% Capacitor Aging
I'd get an 850 watter if OC'ing the GFX cards, 750 if not. Not saying you'll fry the PSU, just that w/ reduced headroom, voltage stability will drop as you get higher and that has a negat9ive impact on PC stability.
