Well, I realize this thread is rather pointless without pictures. Mine's not nearly as "blingy" but here goes:
First off, I received a larger enclosure as the 16x16x8 was out of stock, and it made more sense to me to orient it with the top that opens upward (since you almost never open it after it is completed). I like the horizontal look of things but it did complicate the wiring since the BK/MLT/HLT wiring diagrams are reversed on Kal's setup. Anyway, it's done, now!
Here are a couple pictures of the wiring. If I had it to do again, I would probably cut the wires a bit longer than needed, just to make it easier to route them neatly.
This is the direction I'm going with my "kettles." Two will be keggles and the MLT will be made from an unused food grade 30gal plastic barrel. This means I can actually make 10gal batches of high-gravity beer. I plan to use a mixture of weldless and silver-soldered fittings.
This lid option seemed really cool so I went with it. (I will say that I had a heck of a time with the $5 rivet gun from HarborFreight but their customer service was amazing. After I went through two of the $5 ones, they let me exchange for the $10 one --gave me like $.42 back--and it worked like a champ.) The washers are stainless steel washers that come in orange plastic 2-packs for about $1 ea at HD. I have a plan for the middle "handle" part that involves a lathe, but I'm going to wait to reveal more.
