Is swapping the LCD ok? Processor? I'd expct drives and ram to be freely changeable. I'd like to swap the mobo too, but that's probably not allowed heh.

Technically, if the upgraded part is not a CRU, they can deny future warranty coverage. In practise, though, I've sent in a T42 with the CPU upgraded from a 1.7 to a 2.0 (definitely not a CRU) and they either didn't notice or didn't care.

Good thing then that the problem wasn't with the motherboard. Otherwise they might have replaced it with a new mobo with only a 1.7GHz CPU
