"For all you tweakers out there, this is by far the best part of the 292-3333. With its innovative PCI clamping system, the 292-3333 allows you to install your AGP video card and any PCI or ISA devices without screwing it down. The devices are held in place by a quick release clamp! Need to change video card real quick? Release the clamp, change the video card, clamp it back in place and you're done! No screw driver needed!"
