Custom PC Case?

So, My PC died like a month ago, and I cant live without a PC cause idk, call me an addict idc, but I have no money, so I went thrifting where I could and I found a motherboard (AM4), I still have the ram and ssd from my last PC, so I can save up with that, but fuck me, couldn't find a amd processor (Just found an atlhon II), and Im wthinking of doing a Frutiger-ish PC custom case, Do you have any ideas? I would love too see them lol
