I bought one and installed it in my mac mini. It can be quite a pain to remove the IR sensor. I broke it and thought my mac mini was gone as i did not know i broke the IR sensor at point in time. I thought i had to get a refurbished set to replace my 'damaged' mac mini.
I looked around the forum and found out it's a common issue with people trying to install a ssd because the IR sensor cable is very fragile. You're suppose to lift it from under the wires and not under the socket which i did.
Anyway, i installed the ssd with the data doubler and the mac mini fired up just fine. Only problem is i don't get the white light at the front of the mac mini to tell you that the mac mini is turned on. A blessing in disguise as i tend to leave the mac mini on overnight and the light can be quite distracting in a darken room when i'm sleeping.
