How much resources do you plan to give the machine?
If you're setting up a very constrained machine with little memory, go
with the 32-bit version. It'll use slightly less memory which can be
important if you're constrained.
If you're setting up a medium size or bigger machine (2Gb+ memory),
use a 64-bit version. If you plan you may eventually need to increase
the size of the machine, go with the 64-bit one from the beginning,
because changing from 32 to 64 bit requires dump/reload.
