Wow, so many responses... I'll try to answer everyone. The O2, has a PCI
cage on a daughter card which is 6.875" deep. A 64-bit PCI card with no
overhang will just barely fit.

You can see images of the PCI cage here:

The Millenium I that I have does not fit, physically. It is 7.5" deep. I
already removed the metal cage (only using the daughter board), but the
end of the metal cage butts up against the metal housing, so while I might
be able to fit a 7.25" PCI card this way (though it would be unsupported
and this might not be the best idea) 7.5" is just too big. For example, I
have a 3ware Escalade 8500 which is 7" deep and does not fit. It would fit
without the metal cage (I only mention since its a PCI 64-bit card I have
handy, I know putting an SATA RAID card into an O2 would be silly).

If the Open Graphics Project (assuming this is the OGP you refer to) board
does not have overhang, i.e. it is just the size of a 32 or even 64 bit
PCI slot, it will fit the O2 just fine.
