this little black brick is a full-fledged PC!?! sweet!
micro-ATX: 9.6 x 9.6
mini-ITX: 6.7 x 6.7
just the board!
entire case
M1B: 6.5 x 6.5

my confusion on PCAlchemy though is this: when you purchase the M1B Mini it comes with a Core 2 duo, but when you try to configure it in barbones systems you're only given the option of the Core Duo Yonah. so AOpen made two different nano-ITX(quasi-nano?) mobos supporting the different CPU's, or PCAlchemy wants to promote spending less on the M1B than on a pricier configuration where the only option is for a lesser Yonah?
if i were to build it myself i couldn't get the price much lower than that (after shipping and hassle factors). great job PCAlchemy. good review article on Tom's Hardware too.
