Are you sure about 1080p video and UI2 on the B202?
Out of the box I had success with UI1 and 720p but nothing more taxing.
It'd be better to ask Andrew about that. Because he uses that box in his Cascade System. I'm not sure about UI2 but Intel graphical cards definitely should support 1080p playback.
We have not sold the B202 for some time in fact but it will in fact do 1080p in UI1 or UI2 + Overlay (with 2Gig of RAM) & 512K allocated to video. However because of the GMA950 it will not handle h.264 encoded material at all well even at 720p (mpeg2 encoding works ok).
Unless you only plan to use the B202 mainly as an Orbiter to control other MD's (ie you wont be directly using it for video playback) then if your buying from new i would suggest going for one of the many Intel Atom/Ion units that are available as they just have much more graphics 'grunt' and overall performance is a lot better.
All the best
