I've been wanting to go full Steampunk on something ever since I found out what Steampunk was, and this will work nicely.
I had a hard time coming up with anything I wanted to change on this case (not to blow smoke here, but it's a hard case to improve on). So I figured I'd keep with the basic aesthetics and straightforward functionality of the original designs, and just kick it in the rear.
I want to combine real copper and brass sheeting, rivets, and pipes, fittings, etc. with copper and metal plated pieces of the original case.
I really want to keep the buttons in the original places (unless I got a case and decided they could be better served placed elsewhere, of course). I even liked the idea of turn out feet, which I would probably custom cast from brass/bronze/aluminum to fit the original mounting area.
And replace those fancy new style locks with old school Skeleton key locks, naturally.
And of course, Thermaltake's Logo on the window, done in a stained glass motif. I'm thinking something like roses and the thorned stems in there twisting around. Plus some more colors. Could be pretty cool.
I've already had practice with two of the techniques I proposed and am pretty confident it's doable.
