Destroying my computer in a not so obvious way?

Well, you may be stretching it a bit to try and go for this. But you may be worrying too much as well. Whether or not they notice may just depend on the circumstances, e.g. who exactly inspects it at the company.

I've broken a dvd drive "void warranty" seal and stripped a radeon down to its core. The radeon was genuinely busted before I did so (it had overheated, as I found out), but the drive, as I later discovered, had nothing wrong with it at all. Both were replaced, and nothing more was heard.

Would I try to deliberately bust something, though? Probably not. Especially if the offer includes newer and better hardware.. I wouldn't go for it. But godspeed if you do, let us know how it turns out.

How ya doing, buddy?
