Here's the final version with ventilation.? ?To remove and reverse the bottom panel I drilled out the punches with a 7/32 bit, and then enlarged the outer holes with a 1/4 bit, so 1/4" screws hold the case together.? ?Inside I isolated and slightly raised the heat sinks, and because of the distance to the back I replaced the antenna lead with a bit of RG174.? I'm guessing that wasn't really necessary, but why not.
I'm also digging the fact that as a steel case I can use printable magnet sheets as decals.? ?One of my last projects was writing a program to create rectangular azimuthal maps, which convey the same information as regular great circle maps but with more detail in a more compact and practical shape---handy at QSL card sizes (email me if you want one for your QTH, I can send you a pdf.)? I printed one for Binghamton on a magnet sheet, and it makes a tidy addition to the case.
And here it is working FT8 on the roof of the Engineering building:
