A Petaflop machine in 20 racks?

Quoting from the article:
An ordinary desktop PC outfitted with six PCI cards, each containing four of the chips, would perform at about 600 gigaflops (or more than half a teraflop).
Assuming you were to build cluster systems with six PCI cards each, it would require 4U rack cases... Unless these floating point cards come as low-profile PCI (MD2 form factor)?
20 racks * 42U per rack = 840U / 4 = 210 nodes, not counting switching equipment. Petaflop with 210 compute nodes?
