This may be the most compact Tegra2 fully featured box PC computer thus far. They use 256MB RAM DDR2, 1GB flash storage for 99 euros, they'll also do a slightly higher end version with 512MB RAM and 4GB flash storage version soon. The cheapest board and box could be made for less than 50 euros more. Thus the idea is a sub-150 euro Tegra2 box PC all included and it being slightly larger than a box of playing cards, just big enough to accomodate the connectors.
