I've got an original generation MacBook (MacBook1,1 according to the System Profiler). It's got a 2 GHz C2D, 2 GB or RAM, a dual-layer capable SuperDrive, and an 80 GB HDD. It runs great, I only replaced it because I wanted something with a bigger screen for work. It does have some minor scratching on the lid due to cats (I'll take some pictures). This is the original MacBook, again, so it's only got 802.11b/g, no n. Leopard is installed. Power cord is included, of course, but I don't believe I have the original packaging any more (could be wrong, I'll check the basement). It is covered under AppleCare until August 1, 2009 (so just over a year left).
Apparently these things are going for as much as $1000 on eBay, which seems ridiculous to me, so I'm thinking something more along the lines of $800. But make me an offer.
I live in the Boston area (Porter Square), and I'm more than happy to show it to anyone local if they'd like to see it, and obviously that would make things easier in terms of delivery as well.
SOLD!
