Plus you can get some great deals on pre-built PCs now. In the old days you could save a ton of money building it yourself. But now I just buy a pre-built PC with WIndows 8.1 and swap out the DVD drives for BD drives, maybe add some memory, and then swap out the platter drives for a couple of SSDs. The end result is a PC that costs me less than building from scratch, and more importantly, I've saved a bunch of my time.
The main issue with prebuilt PC's that I noticed was that they tend to have lousy PSU's with weirdo custom connections etc. That's mainly what led me to start hunting NewEgg for a bundle of parts.
