MainGear has introduced a new series of gaming PC, the F1X, which is comprised of the F1X 750, F1X 500, and F1X 200. If the new systems look familiar, it's probably because the F1X lineup uses the same chassis as MainGear's acclaimed ePhex desktop -- in fact, the company calls the F1X a "retooled" ePhex.

The flagship system carries over $5,000 worth of hardware, including an Intel Core i7-975 Extreme Edition, 12GB of DDR3 1333MHz RAM, dual AMD Radeon HD 5870 GPUs, a second-gen 80GB Intel X25-M, a 1.5TB WD Green, DVD and Blu-ray burners, 7.1 channel HD audio, a 910W PC Power and Cooling PSU and more.

Five grand is a bit steep for a gaming rig, but there are some cheaper -- albeit still pricey -- options. The F1X 500 and F1X 200 are $3,100 and $2,250, respectively. Although each machine is appropriately scaled down from the F1X 750, you're still going to pay more than if you just selected the hardware and assembled it yourself -- which doesn't include MainGear's "Angelic Service", of course.
