So this is the progress so far. I have removed the hard drive cage that is in the bottom compartment, I had to drill out some rivets and then dremel cut a couple other bits out to remove it, took a little time. I fit a 240 EK Rad down there. The top started to sag a little too so I made a little strut to prop it up which you can just see on the bottom left image there too.

I hit a snag with my old fan controller, my dual XSPC Rad+Pumps wont both fit with a fan controller as well so I had to get a 3.5" bay one. Its behind the little door you can see on the bottom left, had to cut a hole with a dremel in the cage to allow the cables through for it. Other than that so far so good, just waiting on all my tubing and bits to arrive in the mail and it can really come together.
