DELL Optiplex 755SFF Optical Drive Question

Hey guys, father bought a DELL Optiplex 755 SFF. Only complaint is that my stepmom wants a CD burner. Now i did find a thread and it listed this drive

However, i just want to make sure said drive will fit the SFF desktop, my father and stepmother don't have much money, nor are they computer literate so if for whatever reason it didn't fit, i would get blamed for it. Thanks for the help guys!

P.s. This is the computer in question
DellOptiplex755SFF

Thanks guys,
