Hey Carbide Club
Here are some pictures of what I did with my 400R for ideas. In the end it's equipped with (Alphacool) a 280x30, a 240x60 and a 120x30
First, the case from the outside to give you an idea:
Adding the top radiator meant drilling holes through the case for the fittings to pass through. This was a little tricky as on the 400R where the fittings would go isn't flat. To solve this I placed the radiator with the fittings on and made some marks of were the holes should go and used a center punch (with large hammer) to make a divit so my drill bit wouldn't walk around. Then I used a step-bit to drill increasingly-larger sized holes to accommodate the size of the fitting + hose + clamp. Make sure to get a gasket to fill any gaps between the radiator and the beveled top when using a 280mm rad so your fans are as effective as they can be. Also I had to enlarge the mounting holes as they didn't line up with my 280mm alphacool.
For the front radiator I had to first remove the hard drive bays. This involves removing the front feet (the screws are underneath the rubber pads) and then drilling out the four rivets on the bottom and the four rivets on the top. There may have been a couple more holding it to the vertical frame. I used a die grinder for the ones I couldn't get at with a drill. Then I had to cut the bottom out of the 5.25" optical bay cage, which I used an angle grinder for. Then I created a pedestal using XSPC 120mm radiator stands and some delrin blocks I had left over from another project, milled to size. I also had to enlarge the plastic fan shroud in the front of the case that originally fit the two LED'd 120mm case fans.
Finally I added a 120mm radiator to what's normally the 120mm case exhaust fan location. To clear my motherboard blocks comfortably I used a 15mm depth fan instead of 25mm - if your motherboard heatsinks allow you might be able to use a 25mm.
I have all of the fans on the radiators mounted to blow cold air from the room into the case. For exhaust I used the original two front LED 120mm fans and mounted them on the ventilated side panel. You can use a small screwdriver to push the RPM wire out of the harness, which turns the LEDs off. I used 3-pin fan extension cables to bring power from the motherboard out the rear of the case and pushed the fan connectors through the same grommets so that I can unplug the fans before removing the side panelHappy Modding!Edited by Archea47 - 1/13/15 at 12:26pm
