Yes I was referring to the 524, appologies. CM RR-G524 18 PK R1 Dimensions 144x144x 105mm 5.7x5.7x4.1 inch Superbiiz free ground shipping $35.99 often 15% discount code, I have one ordered to try. Amazon, too.
If you have an oem AMD Heatpipe cooler, these, especially upgraded with a 92mm Arctic Cooling PWM fan glued on in place of the 70mm are a possible choice.
Found this mod on the AMD forums. Fans about $7 shipped, plus plastic glue $5? epoxy.
I have glued 80mm to 120mm adapters to these coolers and used 120mm fans but they do get taller then. My own variation (not cost effective).
Samuel looks like "the" choice, 45mm tall plus 25mm for fan = 70mm in a case using 120 mm fan.
The GeminII at 105 seems a close fit. Stock Heatpipe cooler is about 49mm to the base of the fan, whoch would make it 75mm with a fan on.
