Asmedia can't do raid. So you looking an adjustment among the 2x intel sata3 ports and 2x intel sata2 ports. And don't forget to keep in mind one slot for your BD/DVD ODD, as they will not be happy with asmedia ports!! IMO, more intel ports should have been provided, even though they sata2. At least you could do more with intel ports - i.e., no restrictions whatsoever!!
Anyways, good luck with your build. On a side note; just in terms of overall platform experience, I think X58 is much more stable. At least I found it to be!!
