Hi Fixit, I work pretty much exclusively with Apple products, but was bullied into replacing the optical drive in a 360S.
Having never opened an XBox, I followed your guide to the letter. I completed the job in 1 hour with no problems, broken parts or skinned knuckles.
Keep up the good work guys.
A grateful Ian Younie
