I modded my lego case so that it now holds a powered 4 port USB Hub. It sits on top of the Pi.
The case doesn't look as clean now, but when my legos arrive, I'll rebuild it to be more aesthetically pleasing
I had the same remote and IR Receiver, but I ditched them before I even built the Pi.
I had the Asus mini remote keyboard/MC remote leftover from my previous HTPC build so I tried them on the Pi. Turns out they work great.
The remote is the backside of the keyboard...you just flip it over.
It's only 1" longer than the Pi (.5" longer than my lego case) so I can take the whole system with me.
Where can I find that remote?
