The Intel I7 family, including the E5500 server chips, are screamers. what really counts in large HPC clusters is gigaflop/$$$ a number of vendors make 1U chassis designed to hold TWO compact dual processor server boards so you can get 2 nodes per U, but if you go this route, you really have to watch your cooling and power (50 or 60 of these in a rack means you'll have a REALLY high power/thermal load per rack). An example such board is http://www.intel.com/products/server/motherboards/S5500HV/S5500HV-overview.htm with the Intel E55xx series, you want to populate your memory 6 dimms at a time (assuming two CPUs), using 2gb or 4gb dimms, for max performance (each processor has 3 memory channels) for a high performance compute cluster, you'll probably want to use management software like Oscar, which integrates system management with MPI based distributed computing such that you can manage a cluster of 100s of servers like its a single big system
