In the past few months, we have covered plenty of cool arcade machines and retrogaming gift ideas. This retro style Portable Briefcase Arcade is also worth a look. It is powered by a Raspberry Pi with a case and heat sinks. The machine comes with removable joystick, internal speakers, and battery all in a Samsonite briefcase.
JFCADE is selling these on Etsy. More info is available here.
