Anyone know if the Asus EEEBox EB1020 is fully compatible with Ubuntu "out of the box"?

I'd like to purchase this machine because it fits within my budget but only want it if it'll run Ubuntu. Additionally I've read there are updates for the AMD C-50 which allow the CPU to run as a C-60 with significant performance enhancements. If this is possible with Ubuntu I'd like to know too.

Anyone done this yet?

Thanks!
