My first PC was a pre-built back in 2003 and was based around a AMD Athlon 2000+ and a GeForce MX200 if I remember right. I bought it from a local independant PC shop and it died just after it's miserly 1 year warranty ran out. It was 1-2 weeks outside it's warranty and the shop didn't want to know about it. I knew very little about pc's back then and didn't really know what I was doing but on taking the side panel off it was obvious what had failed from the awful electrical burning smell coming from the cheap ass Mercury PSU they had used. I bought a better replacement along with a hdd as the PSU killed that when it failed and was up and running again. Once I started doing some research it was obvious that they had used the cheapest of everything in that pc despite charging quite a high price for it. The PSU weighed next to nothing!! I vowed never to buy a pre-built ever again and have been building my own ever since.
