As much as I can appreciate the AMD platform (have built plenty for friends and family) the P!!! on BX chipset is still one of the best server platforms available from OEMs like Compaq and Dell. However if you don't have a large budget and don't necessarily need SCSI you can build it with an AMD. I have personally built 5 clone servers and another 5 clone CAD workstations all of which run fantastically considering the servers are mission critical at my work now.
