I want to let people who are interested in the Coolermaster Cavalier Mid Tower know that with an ASUS board running PCIe, they may have to dremmel the back of the case. I noticed that my ATI AIW X1800 could not fit snuggly because there is a lip on the case where the PCIe card goes. It is actually a pretty big lip and took me 30 minutes to sand down. Try placing tape over the holes for the fan to keep as much of the metal shavings from landing on your mobo. Also, use a air can to blow out any left over shavings.
