The bottom holes do _NOT_ contribute to cooling in any way if you have
a PCI card in the case. Because then all holes are covered by a PCB,
thus blocking the air flow of those holes completely.

Radiation cooling doesn't work if you have a quite flat and bright
surface and you have to radiate at least 5W. Especially considering that
the system is designed for 20W, i don't see how anyone would think that
radiation is going to work at all.

Putting the whole case on it's side with additional feet that keep it
a few cm above ground is the only real way how you can use the net5501
if you dont want to use a noisy fan. (Chimney effect)
Alternatively, you can drill holes into the top over the whole length
until you've enough convection to keep the temperature down.
