I found this case http://www.newegg.com/Product/Product.asp?Item=N82E16811215003 when I was searching for a replacement for my shuttle xpc and have been seriously considering buying it. Today I checked newegg for any sales and noticed that it looks almost identical to the praetorian 730 http://www.sundialmicro.com/Cooler-Master-Praetorian-computer-case-rc730ksn1_1701_503.html. Is there any real difference I should be aware of between the praetorian and its offshoot other than the door? If there arent any issues the abs case is cheaper...
