Many people enjoy building pcs and it's actually much cheaper in the long run to build your own pc too. Sure the parts aren't cheap, but in most pre built PCs the parts can be outdated and a little over priced. Plus it's fun learning how to build a PC, and figure out the best parts to get the best bang for your buck! If you get familiar with building PCs, you can even start a PC building business. I've never actually built a PC before though.
