Tyan Tiger 100 is a solid board, but IWill DBD100 has a 1/4 PCI divider that let you overclock to 133Mhz. I am personally using the tiger 100 right now with dual overclocked celeron, filling all my PCI slot with mixed IDE and SCSI devices, pretty much push the motherboard to its limit, but it is still very stable. If you are not into overclocking, Tiger 100 is a great board.
But just one recommendation, ServerWork chipsets will come out soon and should be very nice. Right now, it is already out but you can only buy the version without AGP support. The ones with AGP support should be out soon (actually the MB are out, just that I still haven't find any vendor with those MB in stock and they are usually server grade broad with onboard scsi stuff and very expansive.) In next one or two month, there should be good board with decent prices with ServerWork chipsets.
