Absolutely -- it's like the PC of Theseus. I'm mixed on the motherboard thing. There's at least one instance where I changed only the motherboard, and so that didn't really feel like a "new" PC. I think it was AMD AM3 to AM3+, enabled because AMD retained CPU socket compatibility. I needed a new board for another system, so instead of buying a new "old" board, I bought one for my main PC that was still compatible with my existing CPU (Phenom II ?), then used the old board for the other system. I later upgraded to a faster, newer generation CPU.
