dude, surge protector = VERY IMPORTANT. basically, you paid so much $$ for your system, why cheap-out on surge protection... for a power-bar/surge protector i say MINIMUM $25, though ideally a UPS (Uninteruptable Power Supply) should be installed (for starters a 500VA one is good enough, and APC has some decent models for good prices).
