Last night I did an at-home upgrade on my 1.83GHz Mac mini by going from 1GB ram to 4GB. Everyone was right, it really is easier than you think. The only problems I had were my own fault. I ended up bending one of the ram holder arms when taking the stock ram out and I didn't realize how bad it was until the computer only read the other ram slot. I had to disassemble it again, only this time it probably took me less than two minutes. I didn't want to completely reassemble it in case it didn't work so I only reconnected the audio cable and that other black cable and didn't even put the screws back in before testing it. Well it was about two tests later when it still wouldn't work no matter how hard I pushed the other ram arm and it was at this point that I snapped off the airport antenna while disassembling the internal frame from the housing for the third time! I was so freaking happy that it reconnected as easily as it did because I scared the hell out of myself. Well you can bet buy now that I was getting pissed off, at least with myself. I ended up thinking of unconventional methods. I looked around my room at what I could find. I found a business card, tore one end, folded it up, and put it in between the two ram sticks to push the bottom one down more. To my amazement, it worked! Maybe I pushed it in enough myself or the paper is keeping it down, but it worked! Anyway, I really, really hope my Mac mini doesn't randomly catch on fire because of that. It's the only way I can think of to make it read both ram slots, unless someone else has another idea.
