Yes. I used two plastic pegs to do this as well. Watch out for the wires running along the right hand side of the drive bay (as viewed when you’re putting in the drive) when you’re trying to lift up the drive to fit in the two recesses at the back of the bay so you don’t pull or stress them.
This, agreed. Do as Radioman says. Far less complicated and I had everything apart and back together within 10 minutes.
110% agreed: you don’t have to remove the fan. Those wires are delicate, as is the connector. Just move it off to the side. Do the same for the antenna plate. The fewer connectors you touch, the fewer things you break!
