Nice!! Only think be careful not to cook the caps. It will be hot inside, as there is no ventilation. I had to make holes in summer. You can make a "summertime" cover :-)

I have a thermometer in the case as we speak. Less then 100 degrees F. The wood will certainly not catch fire...as far as the cap go I'm not sure what is OK.

Mhouston, yes it sounds good, but I am only a trained monkey.....

I certainly found with my Aleph 4 that it would run beautifully cool in the winter with temperatures inside the case at about 45 degrees C. However, in the summer the internals would run at closer to 55 degrees.

The simple solution was to fit a pair of 50mm fans (12V) but running them in series. The result is virtually silent and the temperatures keep the caps well below 50 degrees C.

The fans are above the cap banks with large holes drilled in the base around the caps.

reytnz,
That is super neat. I have a long way to go before something I build looks that good on the inside.
