That would be the alternative plan. I did it this way because I have the steel already, and I'm hoping to go as far as possible without spending a dime on this particular build. I could either do the box section trick (if I can find it big enough, which won't be very cheap) or build it out of HDPE/Nylon, which would still be lighter.

I intend to essentially mount everything off these steel plates, the base and top won't be much more than any 1mm plastic, to hold the wires in!

I do have some nice red anodised checkerplate ali which I could use, just a tad reluctant to use it because it's so pretty. :P
