Yeah, it's a very similar setup to my Thermaltake case... almost identical, in fact, though my front fan isn't quite that big.  Also, I put my HDD's in the opposite way around so that all the cables were mostly hidden on the right-hand side [from the front] of the case... it just looks tidier that way.

I had one in one of my bays but frankly I didn't use it often enough to give up the usb connection on the MB so I got a <$15 65 in 1 reader I can plugin when needed and I added 4 more USB ports.....works just as well.

The active adapter runs about $60 US last I checked (been a few months) and they seem to have a limited life span. I dropped about $40 on a 1 GB HD 5450 instead and it runs the third monitor just fine. The last drivers for the HD 4XXX series were just released....no more support for the 4850 so you'll likely be SOL for Windows 8 should you ever decide to give up Veesta and RC.

Close, but no cigar. The card is dead and burried.

But after many failed attempts with various adapters I finally got hold of the right one, and now I'm running a three-monitor setup again!

Next project: Wall mounting the 26" (on the left) and the 22" (on the right) freeing up some desk space.
