100 * 76 * 35mm[3.9 * 2.99 * 1.37inch] DIY Black Aluminum Electronic Box Project Enclousure Case for Digital Amplifier and Portable Headphone Amplifier M Size/Black [Wx-1007635-bk]

This box fits together well, with no overhangs, gaps, or rattles. It looks clean when assembled. Mine had no scratches on the anodization. The end plates are thick enough to be reasonably rigid, but thin enough that they're easy to work with.I did also drill some holes in the top of the box for ventilation, and that took a bit more effort than the end plates, as the material is thicker. However, it wasn't a problem for a corded drill with a nothing-special drill bit.

This box was the perfect size for the project I was working on. It is solidly build, easy to assemble and disassemble, attractive. The metal is not flimsy sheet metal, so be aware that if you need to do any cutting or drilling, it will take some hefty tools/elbow grease to get the job done.

Love the little metal boxes. I use them for audio amps. The size is perfect and being metal they also help remove the heat. They are easy to drill and put together.

Worked perfect for a belt clip connector box for my in ear monitors and headset mic, for those times when I don't need to go wireless.

Decent boxes. I like them.

Perfect size for my project.

Really nice case. Good fits. Perfect for what I needed.

PERFECT
