I upgraded my 10v to 2GB last night, and it was really much easier than I expected. I watched two videos on YT beforehand. When it was time to actually do the install, I had one of the videos playing on a laptop next to me, and I just paused it between steps. Total time for the RAM upgrade was < 30 minutes. DO have a #0 Philips screwdriver at hand. A very (!) small flat blade screwdriver is also helpful for prying loose some of the ribbon cable retainers. A credit card or other thin flat piece of plastic is also helpful for prying on the plastic case and substructure of Mini without marring it.
In summary, while it may look quite complicated, it really isn't too bad.
BTW, of the several videos on YT, the one posted by MyDellMini's own Anguish has the better method, IMHO, as his method installs the RAM without having to disconnect all of the cables to the motherboard. However, his hands are big and his camera angle isn't ideal, so you can't always see the exact part he is referring to. There is another series of three videos posted by someone else who removes the motherboard entirely. His videos have excellent camera angles and are definitely worth viewing for reference.
