Are there any long term effects of having a CRT screen rotated 90 degrees?

Other then severe pains in your neck I'd have to say no.
Just make sure the casing doesnt start to bend and warp the monitor mainboard.

Some monitors do not have side air vents. Monitors need air flow through them for cooling. Poor airflow will reduce the life span of the unit.
