Internal burner,,, maybe?no floppy drive nor internet burner
It weighs almost nothing and the orientation is completely unimportant. Really not much that can go wrong.. works fine for me since a good year 😉I wouldn't just let it sit on the inside, I would secure it especially since SSDs are a pretty hefty investment. Mine came with an "ice pack" cooler that was also a 2.5 to 3.5 adapter.
