I bought one of those off ebay a couple of years ago, and I used it in my machine.
I have trouble with it. Lots of trouble. It may be my computer/keyboard, but I don't think so.
1/2 the time it won't recognize the keyboard when the machine boots and I have to click buttons and reset at the bios screen. I tried setting the Bios different ways, but It's not working well at all.
I bought the ipac for another future machine, I have it in a stand alone control panel, and it works great.
I'd avoid it. One of the other limitations is that they are selling it as they install it. The Diagram is hard to follow and the wires are very short with spade ends. If your CP isn't any bigger than the Xgaming CP you are okay, otherwise you have to extend all kinds of wires to reach.
Craig and the group are really good about standing behind it, but compared to the Ipac, it's no contest.
