I built a $3000 rig for my friend this past November. Went smoothly enough, but it wouldn't post when I powered it up and I swear I nearly had a heart attack! Tried 'everything' until I realized the mobo had a diagnostic LED array on it, and it was simply one of the sticks of RAM not seated 100% right, which is something I'm usually quite picky and careful about. Reseated them and voila, it worked. But damn, I was not looking forward to unplugging and replugging in everything to see what the problem was. Really, really didn't want it to be some DOA component. I really enjoy building PCs, but there is always that risk factor involved. But so far, every system I've built has been fine. [knock on wood] I did buy an iBuyPower PC close to a decade ago. For the price, I couldn't buy the components it came with for what I paid. I ended up transplanting the innards into a nicer case, which is also an easier way for those new to building PCs to tinker without having to do everything from scratch, and you also get to see where everything goes, do better drive/cable management, etc.
