A friend of mine at work ordered a new Mini after seeing mine. He ordered it from Amazon along with 8GB of RAM. I offered to install it since I've installed many including my own. I removed the top no problem and went to remove the bottom and "snap" the right side retainer broke with a little piece of grey plastic laying there. The left side still holds it down and everything works OK but you'd think they could design them a little better than this. I'm no rookie at this and I didn't think I used much pressure but who knows. Just be very careful not to pull out to far when removing the existing sticks.
