t-break has just posted a review of the AOpen AX4T Motherboard which features the i850 chipset for the Penyium4. here's a snip:
"AOpen's philosophy, as far as features are concerned, is based on a pay for what you want. This board supports their Diagnostic LED module, but you'll need to get it separately. There wasn't any option for a RAID controller or Dual BIOS. However, a Network port is built on top of the USB ports for Network connectivity. A USB header is also present for additional USB ports, but the board was not bundled with an extra USB cable to take advantage of the header."
