We don't know what you're looking for, but outside a few minor cosmetic changes (like one RAM riser board being upside down now) and a few technical changes (like SAS drive support, dual 16x PCI-E slots, etc.) Apple's new high performance Penryn Xeon machines -- the Mac Pro and Xserve -- look just the same as they were two weeks ago. Except faster now -- according to their site, anyway. Sorry to disappoint, though, Apple didn't demo the quad PCI-Express slots running eight simultaneous 30-inch monitors. Maybe next time.
