So where do I go from here ?
I have another idea. Your Dell box has 3 PCIe X1 slots.
You can buy some older Quadro NVS 285 or 290 or 295 cards with PCIe X1 interface. Like this one:

This card uses a DMS-59 interface, which splits into 2 DVI or 2 VGA to connect to your monitors.
http://en.wikipedia.org/wiki/DMS-59
With each card at the price of USD $60 or so... 3 of them would be $180 to drive 3 x 2 = 6 monitors. You can buy one first. Try it out. If all works well, get one more to add 2 more monitors and so on. You can limit your risks. For business applications, I think the NVS 285/290/295 are much more cost-effective. You don't need all the 3D stuff on Eyefinity anyway. (Sorry for not thinking in this direction earlier.)
Note: if you buy 3 of these NVS cards, it's advisable to have all of the same make (e.g. PNY Technologies or others), so that you don't run into compatibility issue between different makes. All of the same model is the best. Same make, same model, so the driver software is the same.
Note also that I am not sure if the Quadro NVS 285/290/295 will be compatible with your existing ATI video card. (My guess is it is not compatible.) Which means you may have to take out your ATI card. You can certainly try it before getting more Quadro cards.
Shop around for your Quadro NVS cards. There should be quite a few of them on the market. Make sure you are getting the PCIe X1 version because they also have models that use PCIe X16.
Oh... yeah... make sure your Dell indeed has 3 available PCIe X1 slots. (I only read it from the specs.)
