Yep, that's what most people seemed to do. The manual says that there a couple 
of links that can be made which bypasses the regulators, but for some reason a 
lot of the Atoms I've seen have had the regulators (and heatsink) completely 
removed.

I've got one with the FP ROM and a BBC BASIC card in it, all the others I've 
seen have been pretty stock (although with different memory configs, 
with/without the System bus etc.).

I've never seen one with the colour board, though. I'm half-tempted to build 
one if I can find all the bits.
