On Corsair's stand at CeBit you'll find a version of their Nautilus watercooling system feeding a pair of joined waterblocks attached to GeForce 7900 GTX. The singular resulting block has a water channel between the two halves, needing just one input pipe and one output pipe for two GPUs.

Corsair mention the solution is almost silent (it's hard to hear it on the show floor) and that the waterblock for the Nautilus isn't quite finished yet, but it should be available very soon.

Also in the same ASUS A8N32-SLI system, you can find Corsair's newest 2GiB TwinX kit that runs DDR550 at 2T command rate, 3-4-4-8 timings. Suitable for the overclocker that needs a large memory size (that'd be me, then!), the new TwinX pack, one that uses their Pro heatsink and activity LED assembly, seems ideal for those that need to run just two sticks for overclocking reasons, but also need them to be large and run at inflated speeds.

Just what I need if you're reading, Chris! The module pack will ship in quantity very shortly, Corsair announcing them at CeBit and shipping as soon as they can.

Update - CORSAIR Technology Demo - 8500 2GB (2 * 1GiB Module) Kit (5-5-5-15).
Corsair showcased a technology demo showing DDR2 1066 memory, which will be, when ships will be the fastest DDR2 module avaliable. Corsair is currently shipping DDR2 @ 1066 512MB modules.
