That damn "warranty void if removed" sticker. I wasn't allowed to tinker with the old family Win3.1 PC until 1999 because of that damn sticker, and only because we finally replaced the old dinosaur with a shiny new Windows 98 SE laptop.

The irony is that I regret my decision. 11-year-old me thought it would be a good idea to take the entire thing apart without knowing how to put it back together, so I never did. It would have been nice to still have it around to relive childhood memories...

On the bright side, it sparked my interest in building my own PCs, which I was finally able to do in 2008 after saving up my money. Core 2 Duo E8400, 4GB of DDR2 800, and a Radeon HD 4850. Built it powerful enough to run Crysis. It couldn't run most games beyond 45 FPS, but back then that was good enough for me. These days even 120Hz no longer looks as smooth as it used to. Can't wait for the day when we finally get blur-free 1000Hz OLEDs
