Ordered 9 of these for in-house builds. We have used foxconn, abit, and asus. Nothing matches the stability of this board. All 9 work great, with the exception of 2 that had some sort of startup delay where the fans kick on, then off, then on again. Then it boots up fine. When shutting down, the fans shut off just slightly before everything else and an alarm sounds until you press and hold the power button. We did hear of others having this problem, so we got and used the latest bios and that seemed to solve it. With Q9550 (2.83, 333x8.5 stock) we are able to get 3.77Ghz just using the tool in the bios. Stable in Intel burntest as well as 12 hour Prime95. Video conversion will often bring a system to its knees and cause BSODs where Prime95 doesn't, but with this combination I converted a 22gb transport stream into a 4gb x.264 using ffmpeg and had no errors.
It has a dual bios, so no matter what, you can power up and solve any issue. You can also brand your bios with a 256-color BMP and in a corporate environment it is nice to not have a Monster Truck or Alien showing up first thing when you deploy a system. E-sata is a huge plus also. SATA Raid works very well, although it is slightly slower in RAID1 than I think it should be. But it is stable. Will not ever try RAID0 on onboard raid, so can't comment there.
