(Image credit: Tom's Hardware) For anyone who has built their own PC, you probably know that incredible feeling of accomplishment when you finish. For an enthusiast, there’s just nothing like it. Flipping on the power switch, then pressing the power button on the case, and that sense of relief once you actually see the BIOS screen and watch it all come to life, accompanied by a swathe of RGB lighting illuminating the chassis like a warehouse rave. There's the added benefit of hearing the machine finally take its first breaths, the fans spin up, creating a rush of air through your case.
