The top has a tab with a spot for two rivets initially, but I had to chop that down. Along with this, I brought the whole bottom of the tray and expansion slots up to the last expansion slots height. This, technically puts me at 214mm. Once I'm done the second one, this case will be dual ITX with both a removable tray. I'm keeping the trays up to the size of the CPU cutout on these trays for cable management. I'm also still debating of the orientation of both of these. I have the choice between both regular, both reverse or one of both and have windowed side panels on both sides.
The trays them selves are done, just a tiny bit of sanding left and the paint will come later on. The turquoise paint was only put on for drawing purposes :)
