The Lian Li mentioned above is pretty short but it's deep.
. LC04 is a lowpro case - only takes two add-on cards and PCI only. Uses TFX PSU, won't find one of those w/ much more than 300W. Though you can find them in decent brands, so one may actually have true rated power. Consider all the angles before pulling the trigger.
. What's your plan for this rig? Maybe we can look at going another way... Some of today's microATX mobos are pretty nice...
