I just bought an asus tiny computer. It come with no memory, no storage. You have to remove 4 screw to put it. The RAM is tool-free, which is old news, it's been a while it's old in place by two metal lever hold in place by the lever being springy. The m.2 storage slot was also tool free. Well, it accept 2242 and 2280. The 2242 have a screw. The 2280, which is the size I bought, come over the wifi card and is old in place by a tiny bit of blue plastic. Had to look up the manual
