to my knowledge there are very VERY few 4X I7 slot boards most 4X are Xenon processor boards, also the model the OP posted is a lappy. dunno if the lappy I7 duo core will do you a whole load or good as a monster crack machine but cost will be your factor on a board, a quick google i had no luck finding a 2X slot I7 board for under ~$500 usd. single board and a butt load of ram is what i say, and instead of ri Pi's you could have a field day with a monster network for everything from web server, media server, podcast server,1 or 2 as gateways, bathroom linux box??? how cool would that be?... have fun in whatever you do with them.
