My PC has been fine for 2 and a half years now, I've never had a part overheat or stop working, but I still don't have any replacement parts. So I'm not looking for duplicates (especially since my motherboard is now out of stock and/ or prohibitively expensive), but upgraded parts still compatible with my current gpu and RAM, primarily a motherboard, as these seem to be the parts I've heard of shorting out the most. I don't need SLI or RAID, I just need something reliable that isn't huge and expensive. Hopefully if one piece has a problem it doesn't short out any others. I think the rest of the parts are fine.
