Air Intake Fan . . . Out of Room
For those new to this build, the concept was three ammunition cans stacked together with two cans (main tower) housing the mobo, HD and two fans (intake and exhaust)and the third can (secondary case) housing the PSU. The original concept was to have the intake fan on the side of the bottom ammunition can of the primary case. However, as I dry fitted pieces in the primary case I soon realized that room was a premium and the intake fan mounted internally would not fit.
So I had to come up with an alternative placement. I thought about a fan on the floor of the primary case but ran into the same lack of space issue. I wanted the "air intake" fan low in the case as the exhaust would be at the top. So after some design renderings and a lot of soul searching, I decided to put the intake fan on the outside of the case on the front bottom ammo case.
I was a bit concerned that I was loosing the look of three ammo cans stacked together but when I thought about it, this is a tribute build to the game and while the ammo cans are central, the build is also incorporating items and aspects of the actual game. In the game there are several big fans (I guess air intake/exhaust fans for the Metro) so I figured that placement on the build would still be in keeping with the intent of the tribute to this great game.
The fan was an old Corsair I had lying around and to give it an industrial grit, I gave it a primer coat of "red oxide" followed by a light spray of yellow, more red oxide and finally aged it using charcoal briquette. My original intent was to mount it directly to the front but decided I did not like it sitting there just looking like a computer fan.
So I decided to cover the fan in a shroud which would simulate an intake fan from the game (duct work). Naturally it would have to be beat up, worn, aged, rusted and just plain nasty looking to keep with the apocalyptic theme
. First thing was to build the holding frame for the fan. I used sheet aluminum which I cut, bent and pop riveted to the desired shape.Initial measure/shaping

The next thing I had to do was to create the top cover which would fit over the frame and be used to mount the fan to. The frame will be pop riveted to the ammo cases so I have a way to the get the fan in and out of the build.The templateFinal cutting (all done with tin snips)Fancy bending tool back in action
Naturally, I would need some sort of mesh grill for effect and I just happen to have some old wire mesh lying around in my basement.
Now since this had to look worn, aged, knocked about, etc . . . I did not spare the banging, knocking and scratching while putting it together. Weathering was achieved using a mix of red oxide, grey primer (industrial look)and my favorite weathering medium (charcoal briquette - just crush and rub).
The frame would be pop riveted to the ammo cases over the existing fan opening in order to allow air flow in. The fan would be placed in the frame with the cover secured to the fan (mesh in place).Final pictures
