Cant find my memory card for the camera but here is an old pic without the fans i found on hwbot of my old setup (but gpu,psu,case is the same)
Keep in mind that my current pc is super crap (look at my sig) and the case is just terrible.
I have a Gigabyte GTX 570 Super Overclocked edition With 3 fans on the gpu cooler exhausting the hot air into the case.
I use 2 x 40mm fans at the back as exhaust and one 90mm (or 80mm?) fan as an intake at the front. nowadays i tend to run my pc without side panel so it doesn't make that much diffrence
