What were they thinking?

If you're going to build a computer case that looks like a media player ...

and if you're going to include a big volume control and an LCD player on the front ...

then aren't some buttons like "play", "next", and "pause" also a good idea?

I ask because I was browsing computer cases at the store yesterday, and apparently no-one working for the companies that design these things has thought of including some control buttons on front. To me, this seems like it would rank somewhere in the top 10 most obvious ideas ever, somewhere below "eat when you get hungry" and above "don't pick a fight with a grizzly bear", but clearly I'm missing something.
