SAS (Serial Attached SCSI) drives have been out for a while, but I'd rather have motherboard support, instead of paying for a support card and using up a slot.

Which (if any) MOBO has built-in SAS, the way they have SATA? If they're not here yet, when will they arrive?

SAS is considered an enterprise/server technology. As such, no desktop board has (or will have) a built-in SAS controller.

Most server motherboards don't either, because once you get into SAS, the controllers are specialized -- i.e. how many ports, the feature set, etc. Motherboard manufacturers have found that trying to put a SAS controller on a motherboard is likely to be dissatisfying to most server builders, since they usually want a different SAS controller/card/capability/etc. than what the motherboard manufacturer built in.

Thus, if you need SAS, a 3rd-party card that's designed for the exact task in mind is what you want to buy and add to your setup.

None, at least certainly no consumer boards. What do you need SAS for?

I'm going with a Pentium 8500 or Q9300. Moderate gaming and plenty of Photoshop. I know it's overkill with the hardware, but I want to use it for several years, and the price difference won't kill me.

I plan on running Vista Ultimate and Linux, and I don't want to sit there sucking my thumb while they take forever to boot. Also, I don't want to be bound by disk IO. So I'm thinking of a smallish SAS Velociraptor for the OS and active files, copied over to a pair of 1 Tb. Samsung SATA F1s in RAID 1 for storage. Will I notice any difference with faster SAS access, or should I save my money?

The Velociraptor will be exactly the same speed on either SAS or SATA. Get a SATA velociraptor. It'll be fine.

Some consumer boards are coming out with native SAS: the Asus P6T Deluxe, for example.
