see my post above and my signature then...
but remember that without a case & power, you can't do any of this - building cases under 6u/84-104hp doesn't work out much cheaper than buying one in my experience - & I've built 4 so far... the expensive bits - power and rails (& threaded inserts) take most of the cost
and don't skimp on power - uZeus can be noisy & gets hot - it uses the rails as a heat sink so you need metal rails - and is potentially subject to RF interference due to using a flying bus board...
seriously consider going a bit bigger (6u/104hp) and the befaco excalibus power supply - you'll be set for a while and have enough space to get full size modules - better ergonomics = nicer synthesizer to play with...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
