i have my ic7-g already it only comes with one,, so it would be best for you to go sata hd's ,, thats what i did,, and put them on the intel sata controller not the silicon,, it wont' detect it at boot b/c u have to make sure you enable it in the bios,, but other the n that i would just fork that i would just fork the extra money on buying the sata seagates,, i hope that adapter works,, i mean it does say ic7 not the g ,, and the g version uses serillel 2,, =x but i guess its a risk if it works tell me =)
