Im about 1/3 of the way through wiring my kal build. I lucked out when I bought my enclosure because they sent me a 20x20x8 after the recommended one was out of stock. I feel like the wiring would have been a real challenge in anything smaller.
I also started a thread to document some of my mistakes so that might be helpful if you go the Kal route.
And now you see that Evil will always triumph, because Good is dumb!
