It also has 2 PCI-X slots and I was about to purchase the board you mention in the subject line, but after a bit of digging I came up with these little beauties instead. http://www.startech.com/item/PEXSATA24E-4-Port-PCI-Express-x4-SATA-II-Card.aspx I'm using them in a server, so I used a PCI graphics card to free up both PCIe 16x slots and popped two of these in. They appear to be nicely supported and go like stink. I also used a dual port SIL-3132 board in one of the PCIe 1x slots to fill out my 10 ports. It to is extremely well supported. After I placed the order with Startech, I located identical boards under a "fujitech" branding (Cheap far-eastern supplier) which were/are *identical* in every respect excepting they only cost about $90 each. Cheap and reliable (I picked up a couple of extras as spares). I was replacing 3 x Promise SATA150-TX cards (4 port) which are just flaky in multi-card configurations on anything other than an old PCI 33Mhz bus and I've been very happy with the results. Sonnet also make a 4 port PCIe card using the same chip, but its almost twice the price and uses pretty much the same hardware. These Marvell 7042 chips are great. Cheers Mark!! You can use a PCI-X card in a PCI slot, but I believe you'll be disappointed with the results. If you only need a couple of ports and have a PCIe 1x slot available, the SIL-3132 cards are available everywhere and are really pretty good.
