Here's some pictures of the MacBook I own that has been under the knife. This isn't so much a detailed how-to, more of a what's-been-done. I shall try to give as much info as I can about the changes performed here.
Step 1: The Casing
The casing is available from Speck Products and is called the See Thru. It's available in either clear or red, for both MacBook and MacBook Pro. It snaps on over the case and gives full access to all ports whilst protecting the MacBook.
Step 2: The Keyboard
As you can see, this ain't no ordinary MacBook. A broken black MacBook was recently used to give the keyboard a bit of a contrast. The keys pop off like previous Apple laptops, but be careful as they are very easily broken if not done properly.
Simply source an alternative keyboard, and be very patient whilst changing all the keys over.
I've left the alphabetical keys white as it not only looks pretty good, but allows me to easily trigger clips in apps like Ableton Live.
Step 3: The Apple Logo
The Apple logo was changed with help from icolours. They provide a transparency paper template for you to place onto your Apple portable. With the MacBook, getting to the Apple logo is fairly simple, you only need to remove screws from the display housing. However, the Apple logo on the Core Duo MacBooks were painted white on the inside. Luckily, I was able to source an iBook G4 Apple Logo which fits perfectly, but is clear. I simply stuck the transparency paper on the back and voila!
It looks great in the dark...
Step 4: 11n Card
I've fitted the MacBook with an 11n card from a Mac Pro. This, as well as the Apple Rainbow Logo is warranty voiding territory. They are the same interface (PCI-E v2 or something) and can be swapped out, but it means going into the MacBook and exposing the Logic Board. To be honest, I wouldn't recommend this to anyone unless they knew exactly what they were doing. Apple portables have a lot of hidden screws and latches that could easily brake if you don't know what you're doing.
