Do they at least offer different keyboard layouts?
Explain?
Do you mean when its setup? If so, then yes, I take alot time and care when assembling them and make sure they are set to the region in the world they are bound for.
If you mean different country keyboards, then no, we are in the UK. I would imagine it would be a nightmare to source keyboards for all round the world.
If you dont want a keyboard & mouse, you can always ask before ordering.

Any idea if the Sam 800 is actually quicker than the 733?? As I understand it only the 733 has the quicker Ram clock? is there any benchmark testing between both?
I'm torn on which to buy 
Without running a benchmark, I would'nt know.
Why not ask Acube, they made the board.
