I did a quick google and found this post on the overclockers forum. The first poster has a silver arrow and a coolermaster cosmos 1000 case in their signature. I have the silver arrow it's a great cooler, but is big. Sorry but I have no personal experience of that case. Try looking through this forum it looks like the silver arrow club with over a 100 pages. Look through there must be someone there with that case. Happy reading.
