Here is my used 15.4" MacBook Pro, June 2007 model, which is the A1226. Please read through the full description.

Spec:
 - 2.2 GHz Intel Core 2 Duo Processor
 - 320 GB Hard drive
 - 4 GB RAM
 - 128 MB NVIDIA Graphics Card
 - 15.4" Display
 - Slot Loading SuperDrive
 - Has both firwire 400 and 800 sockets
 - 2 x USB 2.0 Sockets
 - MagSafe power connector
 - iSight camera
 - Fresh install of OS X 10.9.2 Mavericks

Condition:
 - Battery is totally dead, and needs replacing. Do not even attempt to run this on battery. It runs absolutely fine if you always use the power lead though. You can find replacement batteries on eBay very cheap.
 - There are small dents in the top corners of the screen casing (as pictured)
 - There is a strange white mark which can be seen on the left edge of the screen if looking closely (as pictured)
 - The head phone socket seems to stick out by around a millimeter, but I think that might be how they are designed as it has always been like that (see picture). It does work absolutely perfectly though.
 - Superdrive sometimes takes 2 attempts to eject a DVD, but otherwise works perfectly.
 - Seems to be one screw missing from the bottom casing, but it's never been a concern.
 - Two of the tiny rubber feet from the bottom casing are missing.
 - Usual wear and tear, has slight scratches and the odd minor dent around top and bottom casing (see pictures)
 - I don't think the power lead is a genuine apple one, but is magnetic and works absolutely fine.

History:
I bought this second hand last year, and have loved using it for various music projects. It's a very speedy machine, and I love the fact it has both kinds of fire-wire ports. The reason I'm selling it is because I no longer use it, so it's just sat at home, which is a terrible waste of such an awesome piece of kit.

Postage:
I would prefer for you to collect this so that you can see the item working and can ensure it's safe delivery. Alternatively I might be able to drop this off to you if you live near enough. You can arrange courier, but note that I will not accept refunds, it is at your own risk, so I would recommend against this. Please get in touch if you would like to arrange any kind of postage.

Returns:
I have very clearly described the item, and given plenty of pictures, therefore I will not accept returns.
