Yeah. I never actually took apart my Ti's screen housing, but I did seriously investigate it when researching whether I was up for DIY-ing a screen hinge repair. TL;DR, I ended up having it professionally done, and even the pro left plenty of evidence that the machine had been taken apart. Definitely not worth doing for a "cosmetic" problem.
There is an important rule of thumb to remember if you do ever take the housing apart: if your laptop has the original Apple hinges replace them while you have it apart, preferably with one of the improved third party replacements if you can still find them, even if they seem okay *now*. They *will* fail eventually.
