Chosen Solution

I’m trying to fix my wifes computer as it fell the other day and started saying it couldn’t read the hard drive. When I checked it out I realized the back cover is only held on with maybe 3 screws, and for a kicker the hard drive isn’t screwed in either. I pulled one screw and put it in a new spot which is working for now but I’d like to reconnect the rest of the back as well. When I referenced the teardown guide below it listed that they are 2mm phillips screws, but didn’t give me lengths. I’ve found some bundles that are 3mm, is that long enough?

@patton93 should be a M2X8mm
