Using both intake AND exhaust fans is a waste.
In fact, if your "cutouts" on the miners are tight enough, you might not need additional fans at all - the fans of the miners should get your air circulation going.

You WILL need more space for air intake and exhaust though if you are planning to run 600 AMPS worth of 220V mining in that room - most likely you'll need to replace BOTH windows with louvres or some such.

Breaker panels on the cold side and well away from the window is a VERY GOOD idea - don't change that part, except perhaps to put ALL the panels on the back wall not just 2 of the 3.
Breaker panels CAN be mounted in a vertical stack, if you leave enough space between them for wiring access - the code spec for "required height" is pretty wide.

Thanks for your input. I do plan to make it as tight as I can. Of course will try to seal it in air tight with some good sealant in areas that are hard to 'maneuver' around.

Yes the breaker panels will go on the cold side at the back wall. There were some updates so now going to do only 2 200 amp panels instead. See below as I will post updates on my adventure. I hit a snag on the electrical portion, but already have solution and hope to remedy by Thursday this week.

The windows are completely removed and boarded up. We installed fans. See my updated posts following this one.
