Hello ifixit... I need to source the chassis screws (4) that hold the main assy to the base. An authorized repair outlet that I foolishly permitted to work on my Mac mini didn't reinstall them - threw them out! They actually told me that they're not needed, to which I immediately deleted them from my rolodex... Please tell me you at least have some sort of 'screw kit' for the Mac mini? Trying to find them is a major pain... Pls advise. Thanks in advance. Chas Hulme
