Here's revision 3 of my old case. It's still a work in progress, but has some really cool stuff to it. I made the hoodscoop by hand. I made the basic shape out of styrofoam, then covered that mold in masking tape. then I hand laid fiberglass on the mold, and finished it out with bondo (fiberglass resin gets harder than I felt like sanding). Inside, the radiator has a fiberglass fanshroud with 2 120mm aluminum frame fans mounted at an angle. That shroud is slid over a 1977 pontiac bonneville heatercore, and it does a pretty good job getting rid of the heat in my rig.
All the diamond plate is real aluminum.... not the contact paper stuff, even though they are getting the contact paper stuff looking pretty real these days. I have the side panels painted, but I am changing my mind about them right at the moment. I will ditch the flat look for a couple of fiberglass ducts towards the top. i think I will put a 120mm in each door inside the soon-to-be ducts, with the vents blowing towads the back (exhaust). Then, I think I am going to make some gauge pods for the bottom of each side panel, and mod a Musketeer to put two of the round gauges in one side, and the 3rd round gauge in the other. I'll keep it looking even by modding the fan control sliders onto a round faceplate (same as the other gauges), and put it in the side that only has one gauge.
like I said, this is a work in progress, and it's my main rig, so the wiring is a mess. Also some pictures are a little older than others. I have the power and reset buttons mounted on the front now, even though some pics don't show that. Also, the yellow thing above my DVD burner is the hard drive cage.... still a little rough, but I was in a hurry. It mainly consists of the original cage from the case (the removable kind with the lever-lock) with the top, including the lever, cut off to fit the space above my DVD burner. Then I made a fan mount out of plexiglass, and heated it up to bend around the front of the cage. It actually has flames cut into the plexi.... but you can't see that while it's in the case.
As you can see, I still have to move the waterpump. I am gouing to make a bracket that will mount it right behind my bay res, upside down. and the wires need cleaned up.... I said that once, but it is nasty enough to mention twice.

And don't mind the mess, I am a slob.
