i haven't bought a computer from a major manufacturer for a number a years, because i find it cheaper to build my own. i remember getting a family computer and it would have a void sticker on the case. my sister got an HP and when she went to college, she needed an ethernet card put in it. she had the college computer place do it. they called her about 3 times to see if it was ok to break the sticker. i don't get it, why would they even put a sticker on a pc, it's so common for people to open it up to upgrade or add something.
