Well, since no one has posted in the other thread since May, decided to post a few things here.
First, latest Hack is an HP/Compaq DC7800 which I got off Ebay for $69.90 shipped. I first installed iAtKOS L2 on it and it ran great. Thought I might as well see how well a retail install went and did one using UniBeast and another using Kakewalk.
Then when Mountain Lion was made available on the app store I bought it and since have also developed a UniBeast guide for installing on this same system. It runs very nice, but with the oddball sound chip, you can only use voodoohda or even better a USB sound dongle. Guides available on the HQ-A homepage linked to in my sig.
BTW, I also tried to put ML on my DS3L, but so far I have been unable to get it to boot after installing ML. I'll keep working on it though.
So far that is all I have ML running on, but plan to try my GA-945GCMX-S2 and GA-H55N-USB3 also very soon.
