I paid something like 80,-=E2=82=AC (excl. VAT). Oops, you're right, was reading the model numbers wrong. The LSI1068-based one is only $129 CDN, the Intel IOP-based ones are $200-300 CDN.

Urgh, I have yet to find a riser card that will plug into a Tyan motherboard and not cause issues. Due to all the issues we've had with riser cards in the past, we have sworn off all riser cards. For our 2U servers, we use low-profile cards to avoid risers. I'll keep looking for a PCI-X card. These look like they'll cover our PCIe needs. --=20 Freddie Cash fjwcash@gmail.com
