I have tried this, but I have found that in practice, the cost of selecting a suitable motherboard, graphics cards and configuring and maintaining such systems offsets the cost gain in hardware. You have to pick the hardware carefully since PCI cards are becoming more difficult to obtain, and so you ideally need a 6150 class integrated graphics HTPC motherboard with dual monitor output, with two suitable PCIe slots for two cheap 6200 class dual monitor graphics to allow 6 seats, without going to SLI or hard to get PCI graphics cards which will destroy the concept of cost gains. The setup is also likely to break often with OS updates which means high maintenance costs.
At the end of the day, I found it not worthwhile for commercial provisioning compared to thin clients http://www.ewayco.com/0-embedded-systems-prod-pages/vx-thin-client-embedded-system.html or ultra cheap sub $200 PCs http://www.walmart.com/catalog/product.do?product_id=7754614 because labour is a lot more expensive than hardware. It is also less flexible because the VGA cables have to be short.
You can try a proprietary product which does work
http://www2.userful.com/ but it isn't glitch free and I don't believe it provides two seats with two headed nVidia cards, and those that it does support for two seats per card are expensive or difficult to get hold of. This means 2 or 3 seats only per PC. Also it isn't glitch free, although it is vastly easier to set up than the do it yourself approach.
