I just did work on my first Mac Mini last week for a client in Bolingbrook. I read up on the procedure prior to going to work on it and it was pretty straight forward.
Getting it back together was a bit of a challenge, but I finally got it to snap back into place and all is well once again. It was a simple procedure, upgrading from 512MB of RAM to 1GB of RAM as well as some one-on-one time with the client.
I've been doing much more photography, video and PC work lately though. Some of my video work is up online now so I'll post links as soon as I take the time to get them.
