Intel's looking at BTX to replace ATX as the desktop form factor.... We
have a year or two till it's serious, but prepare in advance. :)

Short version, expect these things in the final release:

- No AGP Slot (PCI Express instead)
- No PS/2 slots (USB)
- No Serial Ports (USB)
- No IDE ribbons (Serial ATA)
- Card slots are now on the opposite side of the M/B, so using existing
PCI cards will likely be a problem.
- Versions for Full size, Half-size (like the old Dells) and Small form
factor (like the Shuttle boxes)

Basically it's a start-over from almost scratch and legacy is being
removed. Interesting stuff.
