I currently have an ITX mobo in a 350D as I was planning on going mATX before realising nearly all available 1150 mobos have PCI slots, let alone m.2 support.. So wanting to solve some issues! The plan is to create a clean mid-wall cover that will be held in place by the motherboard stand-offs to cover up the CPU cutout (larger than the motherboard!) amongst other bits.. I know there's quite a few people who have done similar things on here, so was wondering if anyone had any advice?
