First off to answer all the questions up front, yes, this case is fully capable of housing some of the bigger models of graphics cards. Even though I didn't pull it from my work rig, my GTX 280 would have no problems fitting at only 11" long. For the build purposed i used a smaller card, I just wanted to point out it wasn't due to it not fitting.
For my installation I have a lot of older IDE drives, and due to the cage being able to be moved I was able to get the optical dive installed in the middle slot but when I went to install the ribbon cable I realized it was wishful thinking. The cable wasn't long enough, and for review purposes it was easier to just raise the cage. Nice to have that option!
Fast forward through a bunch of "no thrills and no surprises" installation leaves you with this, the completed package. I could only find a couple things to address here. For starters I would have liked a way to get the top and rear exhaust fan power wires to the rear of the case neatly. Second is that I had to really stretch the audio cable to get it mounted to my motherboard audio header. I would have liked just a bit of slack in my wire, but it does at least get there. As you can see I went sort of half and half with the wire management. You can either bundle extra wire under the HDD cage, or pass them through to the back and use the supplied ties to hold them in place and out of the way.
Here we have the back of the Fantom completed and ready to run, minus one thing. I seem to have misplaced my rear I/O shield for this board, but you get the idea. As you can see the Fantoms's rear mounted PSU design even includes blackened thumbscrews for the installation. Just another step AZZA took to make things a bit easier on the user.
Wire management was very simple and the holes cut in the tray correspond nicely to drives and graphics card power needs. As I say if I had routed all the cabling to the rear of the tray, I have the whole right side left to use to strap them to the tray also. Even with routing the 24-pin motherboard power supply wire along with the front I/O panel wiring, I was still able to get the rear panel back into place with relative ease.
Here we are again back around to the front, this time in completed form ready to receive some power and accept the fresh Os install the PC so rightly deserves. Just too bad this door isn't reversible.
