100% plan on using your own mounting hardware. What comes with the cabinet is two screws with cheap plastic anchors - not sufficient to hold this weight. 
The wall where I wanted to hang this had no studs so I used molly screws and it worked really well. There are two pre-drilled holes in the back for mounting and I actually added a third for safety. 
The actual cabinet seems pretty sturdy. TONS of pieces to assemble but it was really easy and the illustrated instructions were complete.
