This should replace one of the slabs in the garage wall directly,
Is the fan for dust removal or heat removal?
If you try venting electronics outside you will end up killing your electronics with condensation, which would be bad. :(
You can mount a closed loop radiator externally for heat removal, but air is a no-no.
