Since I'm planing a scratch build and have already posted some post with questions for it. Though to not make to many posts I will make one post and ask my questions here instead. To get a pre-taste it will be a large water-cooled black painted aluminium with plexi details that will be light up with with blue and red LED:s, wasn't my intention when I made the design but it is actually kind of Tron inspired Will also paint one of the sides with a custom paint job since I have a friend that is really good on using spray cans to do some real art with I'm currently doing some planing in Skecthup and I'm not sure what thickness I'm going to use. So the main frame will be made from either 10 mm or 15 mm aluminium square bars. Then I will use 1mm aluminium plates on the sides with a frame around them that will be 2 mm plexi and then topped with another layer of 1mm aluminium. So here's the first question. Will 10 mm aluminium bars be enough or will it be unstable? For the stability should you go with 2 mm aluminium for the base plates or will it be enough with only 1 mm?
