Yup - count me in as one happy monkey. Added a 40 to my 20 last week. It took about 30 minutes, and after watching me do it, my brother got me to take his to bits to reseat the drive cable, although he may end up having to get a new cable - it seemed fine.

Piece of cake (even though I knew I didn't have the right jumper...I lost the one I was keeping for the job. Well, they are very small)

Next development - lit buttons. I reckon Brian doesn't have me on his list, so I'm watching the various threads on the topic.
