My main laptop is a 51nb x2100. It's a ThinkPad x200 with a modern motherboard and 3000x2000 screen hacked in. I installed a JIS keyboard, since I like the green text on the alt keys. It came with a glossy display from a ThinkPad x1 tablet, so I cut out an antiglare screen protector with a utility knife to give it a matte finish. The edges weren't completely straight, so now I've replaced that with a custom cut antiglare tempered glass screen protector.
