mini-itx is (a lot) bigger but the Atom (a rebadged centrino) is a nice chip. Dual core version actually two separate chips (not even on same die) and with hyperthreading shows up as 4 cores in Ubuntu, so it's a tempting piece of hardware for more demanding users. We're releasing that board in a sealed, fanless box with a 30GB OCZ SSD. Will be the P1 - should have videos and pics on the site by the end of the month. But naturally more expensive and more power-hungry.
