Here are some photos of my completed MP3 portable mini-amp. The box is approximately 5.375" x 4.25" x 4". The actual amplifier is a class D assembly I ordered on ebay from China; I removed the input jack, removed the power jack, installed the power terminal block, and changed the LED.

It is quite loud, and clear. Of course there is very little bass, but I use it mostly for listening to podcasts, so that's not a problem.

ETA: The hardest part was smoking all those cigars to empty the box.
