No I did not. I am using the existing 90 by 160mm intake in the front. My core is located behind it. Of course, to get to this setup I had to adjust some things on the inside.
The dual 80mm intake fans on the front are gone, as are their support point in the chassis. The lower 4 3.5" bays are sawed out as well, up to the point where the lower external 3.5" bay has a folded lip. Note that you'll have to take out the bottom of the case if you want to do this, which involves drilling out some 8 rivets.
Another handy thing with this case: you can run the power cord for the pump out of the back using the small gap in the lower bottom corner near the PCI slots. Normally the side panel will cover this, but you can saw off a small piece that folds over this gap without much effort nor destroyed looks.
The bottom line is that with some effort you can put a full-fledged heatercore with 38mm depth fan and shroud, a big pump, a T-line and a 3-barb block with all 1/2" tubing in there. In my opinion, the end result of great cooling in a stylish case is worth the trouble.
