Yes it is dusty and shameful, but in my defence (it's no defence at all really) I've been having drop outs on my Hyper X ssd which is why the sides are off, the 7970 is a complete dust magnet. I'm sure there is other stuff I could blame but it's just bloody laziness.............the dog! It's entirely the dogs fault.
I'm keeping the 180 to see if I can put a pair of 240 rads in the basement of it, hopefully cooling a pair of EVGA Watercooled 280's...........not sure why but mostly cos I can.
