You could also take the compressor out of the casing. Makes it less heavy too
I am afraid you can't... you'd have oil flying everywhere...
plus the casing serves quite a lot of other useful functions too
Im afraid an open fridge compressor is on the floor right next to me, still capable of doing its job.

Why is underpresssure better than overpressure?
I'd say the increased density of the air with overpressure would make be more capable of transferring heat. The pressure differences are minimal though.
I'd set it up something like this:
| Compressor <fan<
However, make sure all air that goes out of the top HAS to pass the compressor. In the pics you posted with all the fans in the sides, the big fan will exhaust air out of the right hole which doesn't even pass the compressor! So put the fan in the left side, a fan in the right hole in the top, and close the left hole.
Maybe it would be even more effective to do:
| -big hole-
| Compressor <multiple fans next to each other<
Two parallel fans have more flow than two fans in series.
