So I have been using my pi 3 on my TV and purchased a second one for a bartop arcade.But I want a small portable bartop like the picade, but they are very hard to find now. Where can I find the kit without the screen? I live in the USA. Or can some one give me some measurements so I can build my own? You can see by the numbers on the arrows what measurements i need. Sorry but they are hard to find and don't see any with 12'' screens like i want.
