Check around to see if Supermicro has a regional sales center for your local. They have a new line of servers setup for GPU based HPC applications... I have no need for such horsepower, but reading the specs makes me envious none the less: http://www.supermicro.com/products/system/4U/7046/SYS-7046GT-TRF.cfm?GPU=TC4 Dual 5500 series cpu (four core each) plus four nVidia Tesla GPU based supercomputing engines (included). If your application can't support GPU based processing, I think Peter's suggestion is most fitting. Load up a rack of dual socket 5520 servers from Dell or HP and then save some money by building your own shared-storage to feed the cluster. The big vendors crank out very inexpensive dual socket xeon servers, the only area they really seem to be price gouging in right now is storage. Gordon
