Congratulations.
Quoting myself from a thread several months ago, here's some ideas for
rebranding 2,1s that I'm kicking around to use for selling them on eBay:
You can put a decal on the lid with the Trisquel logo on it for the Apple
logo light to shine through.
First, download the Trisquel logo from here
https://trisquel.info/files/trisquel.svg
Second, go to this page for a custom laptop skin maker that matches the
MacBook's size. (I used a generic template rather than a MacBook one so as to
not have the cutout for the Apple logo, since we want to cover the Apple logo
up.)
http://www.skinit.com/create-your-own/custom-skins/laptop/generic/custom-design-generic-13in-12-803in-w-x-8-996in-h-laptop-skin
Third, click the "Upload" icon on the left side of the screen, navigate to
the Trisquel logo you downloaded, and upload the logo into the custom skin
designer.
Fourth, click the "Scale -" icon at the bottom of the web page (you may need
to scroll down to reveal it) enough times to get the logo down to a normal
size. The default background color should be white, so you should be already
set there.
Now you're ready to complete the process and order the skin.
To cover up the word "MacBook" on the bezel under the screen, I'd recommend
putting one of the Trisquel logos that has the name of the distro beside it

onto an SD card or USB stick, then print it out in a small size on photo
paper or card stock at a photo place (unless you have a photo printer at
home).
Then carefully glue it over the word "MacBook".
Add a Trisquel case badge from here

Cover the iSight camera lens which can't work in freedom

And now you're silently, attractively, and proudly advertising Trisquel and
freedom instead of giving your endorsement to Apple's lockin policies that
have made it the richest company in the world at the expense of user freedom.
