MacBooks tend to look very similar, and it's important to know which machine you have before ordering any replacement parts.
The MacBook Pro 15" Mid 2009 2.53 GHz Unibody's case is composed of aluminum, just like the laptops before it. However, the case is machined out of a single block of aluminum, following the same process of the MacBook Unibody and the MacBook Pro 15" Unibody. The Unibody revision also introduced some features that were never before seen on an Apple laptop: the inclusion of dual video cards (one for regular use, one for graphics intensive applications) the Mini DisplayPort (which replaced the full-size DVI display connector), and larger hard drive and RAM capacities.
