Wow, they're working hard over at Anandtech, bringing in tonnes of Computex coverage. They kicked things off yesterday with some earlybird coverage, including a sighting of a BTX AMD motherboard:
One concern we have all voiced is the lack of AMD motherboard designs for the BTX specification. Originally we worried that routing would be an issue thanks to the Athlon 64’s on-die memory controller, but MSI put our fears to rest by bringing us the first Socket-939 BTX motherboard we’ve ever seen
They don't stop there, with sightings of RAMdisks from Gigabyte, multi-GPU video cards and more.

Things continue for Anandtech today, with day 1 coverage, including Iwill's server kit, AMD's stand, and a wall of motherboard with Intel's 945 chipset. If you don't like reading, worry not; there are loads of pictures to look at.
