I would guess not. The bulkhead fans run about 17K RPM and blast everything
behind them with fresh air from the intake. The front CPU fan blows on the
rear fan. It looks to me it needs a lot of airflow. The PSU also cools the
case somewhat with its two fans.

Looks to me a lot of engineering went into getting air into and out of the
case. I don't think it can cool sufficiently without a case, or with the
case open, but OBP will probably shut down before anything bad happens.
