Although the current CeBit 2009 reports 25 percent less exhibitors and an about 20 percent smaller floor space, there are some interesting things going on. Just have a look at the "P6T7 WS Supercomputer" motherboard from Asus, for example:

 Besides supporting the new Core i7 processors from Intel, this X58 motherboard features seven PCIe 2.0 x16 slots. While three of these are "only" running at x8, the other four slots support full x16. Whether this makes sense or not is questionable, of course. Other specifications include: six Dimm slots for up to 24 GB of DDR3 RAM, six SATA 150/300 ports (supporting SATA RAID 0, 1, 10, 5), two SAS ports (supporting SAS RAID 0, 1, 10), two eSATA 150/300 ports (supporting SATA RAID 0, 1, 10, 5) and two Gigabit-Ethernet-Ports.
