I was pressured to post this quick little build, even though I don't have any hardware and it will likely go straight to storage. I had some time to kill, and some scrap materials to get rid of, so I thought I'd build ol' crusty. A while back, I tried to get rid of some cast aluminum outdoor speakers at the local Goodwill. Apparently they have a policy against taking anything slightly rusty, so they stayed around as garage clutter. On a whim, I checked to see if I could fit an ITX motherboard inside. It turned out the fit was perfect, and I tore into the speakers so violently I have no pictures of the start of the project. -Here's the inside of one of the speaker back panels. I have already sawed the mounting pegs and stuff off the inside here. The plan was to take the two speakers and attach them back-to-back, then use the backplates to make faceplates. -I had to sand the faceplates down a bit to fit them in the raised border on the speaker fronts. I pried the metal mesh of the fronts and tossed it immediately. That's some of that stuff there's no pictures of, bear with my rambling for a bit... -A back becomes a front, and a back becomes a back again. -what? I added an 1/8" bit of plexi scrap to get these flush with the lip. I have some nice metal from a control panel for an old X-ray machine here... No, I don't have the X-ray part. I had to remove some spot welded reinforcements off the back. These bits are to splice the two speaker bodies together. -I drilled the body holes first, then traced the hole pattern onto the splice. -Here's a good size reference shot. I countersunk the holes so the expanded bit of the rivets would sit inside the splices. Grandpa's safety goggles served me well for this project. The sander throws filings straight up and forward, so even sitting off to one side you end up looking like Ziggy Stardust. -I clamped the halves together while adding the rivets. -There used to be grit on this poor sanding drum. I used it to remove some of the rear speaker face. (the whole back-front thing is giving me hell.) -I got this far with the sander and a jig saw. The aluminum is close to 1/4" near the edges. -I filed on the edges for a long time. I filed the rivets down even with the splices too. The extra room will be needed. -I have the fan already fitted in this pic. The speaker mount was almost a perfect match for a 92mm fan, and I have this insano-thick 92mm fan I want to use. I'm fitting a box for the power, LED, and USB. This was originally an order-clearing button box from a certain local fast-food establishment... Are you keeping track of the sources yet, 'cause it gets better. -Some work on the switchbox. I've blasted the entire setup with oven cleaner at this point to get the "crusty" effect. The switch was originally shiny nickel and stood out way too much. I tortured it until it matched the rig a little better. -I added this spacer to make the switchbox and the fan level with each other. -What is that? It kinda looks like a tiny engine head... -Yup. It was once a weed-eater engine. Here I'm chopping the top off of the itty-bitty piston head. The plans I have for that will have to wait for the next update.
