There's a reason for the price difference, other than MHz. The DKB boards needed a firmware update to run OS3.1. So with the Cobra, unless you are lucky to find one with the update, will have you stuck in OS3.0. Then you'd need to figure out some clever way of soft-kicking into 3.1 so you could install 3.9. I've never done it, maybe someone here has found a way? My advice, bite the bullet and get a Blizzard MarkIV (or better yet a Blizz1260). btw, since BlizzardPPCs with 68060s seem to be fetching only around $350-400US right now on eBay, you might want to bite a little harder, pay roughly double what you'd pay for a 68030 and have a real monster A1200 (provided your not limiting yourself to just an A1200 desktop original).
