I ordered one and it should be here on Tuesday. I'll know for sure on the fsb then. Supermicro's site does not list a parallel port on either the 370DLR or DLI (I downloaded the manual, it does mention one there). So I don't think that's a factor. Axion's ad clearly states that it's 133mhz fsb and I don't think they'd put that on there if it wasn't, they'd just leave it off. As far as the memory goes it needs registered ECC SDRAM. And yes, it does have dual nics on-board along with the ATI Rage XL 8mb chipset.
Edit: Either way I'll probably keep it.
