Laser Controller box position question

Hi Community,
I recently got my 50W Cloudray fiber system, but the problem I have is the Controller box is to tall to fit on the under shelf of my work bench like my 30W Fiber. My question is can I lay the control box on its side? I cannot think of a reason, everything in it is solid state and it will not change or inhibit the airflow.
Thanks,
RIck
