I cannot find any information on the length of the sata bay. Can it fit 9.5 mm drives or is it 7mm? It's insane to me that this is straight up impossible to find an answer to online or in the manual. What freaking size drive fits into the 2.5 Sata bay??? There are 7mm and 9.5mm ones. The official Crucial upgrade parts are 7mm drives but they come with 9.5mm drive adapter so which **bleep** one is it???
