This listing is for a power amplifier case that consists of the following parts:

The chassis has 6 M3 PEMs pressed in to mount the cover to. Additional holes punched to included; transformer, heatsink, inputs, outputs, mains switch, IEC mains inlet, feet, front plate mounting. The case can be configured as a stereo or mono amplifier.

We are in a position to offer a complete kit if preferred. 

There are two obvious heatsinks that can be used, see photos for part numbers. The larger one needs the end fins cutting off because it is fractionally too large. It does though offer the best cooling, especially if you want to build a stereo amplifier. Rated at .45 K/W

The smaller heatsink is rated at 1 K/W

Both need to be taped underneath and on the face to secure the amplifier bracket and fix to the case.
