What is the best gaming desktop ?

Falcon Northwest FragBox

he hand-assembled Falcon Northwest FragBox is highly customizable and aims for superior performance while keeping its physical footprint small.

Many years ago, I was one of those guys who would build my own gaming-oriented desktops from the chassis up (my first had a 3dfx Voodoo2 graphics card). But in recent times, I've been fairly satisfied by off-the-shelf gaming laptops, even with the compromises inherent in those systems.
With the component calendar page for both CPUs and GPUs flipping at about the same time, the introduction of new parts from Intel and Nvidia seems like an opportune moment to take another look at a dedicated gaming machine, in this case the FragBox from Falcon Northwest.
This is a small-chassis desktop, which means it's about the size of a bread box (to use a particularly dated reference). Full-tower desktops, gaming and otherwise, still exist, but I can't imagine carving out the space for one of those. This smaller size feels like the most appropriate compromise between power and semiportability.
