Rip offs. A $100 and a $200 cpu bundled with a meager bit of basic generic components. The video cards are email/surf net worthy at best, 128 bit are you kidding me? (that's like what $70), a card reader you can get for $10, a DVD burner for $20, a hard drive for $50 and an OEM copy of Windows home premium. First rig has 4GB of DDR2 RAM (speed not even specified in either deal). And don't ask me why they put a socket AM3 cpu in a mobo that uses DDR2 when most use DDR3 (and that RAM is cheaper lol) All stuffed inside a cramped case. Then you have to shell out more $$ for a monitor, maybe even speakers and a keyboard/mouse setup that won't destroy your hands. They're both awful.
