Selling off the various working parts of my 2008 MacBook.
The motherboard died and I have already removed the hard drive and cooling fan, but all other parts are available, including:
13" screen (not Retina) - $150, OBO;
DVD CD reader / writer - $50;
Aluminum Unibody inc. keyboard - $50, and;
Battery - $25 (the battery hasn't been charged in several years, so may be useless)
If you have an existing A1278 MacBook / Macbook Pro, I can probably help you install the parts to ensure they are working properly.
