Or at least it felt like that. I've just finished upgrading my Mac mini with an extra 1GB of RAM.
The little thing is so damn crammed inside, it's amazing. I mostly just followed this great tutorial - take a look if you're curious how it's done.
Well worth the trouble though, as it cost me half the price compared to the upgrade option at the Apple Store, and I'm even left with two new 512MB SO-DIMM sticks. Anyone needs those?
