Can I stack my EVO CD and EVO 75/150 on top of each other?

Yes, you can stack the EVO CD and EVO 75/150 on top of each other if you wish to do so.

While you will be able to stack the units either way without issue, we would generally recommend placing the EVO 75/150 on top of the EVO CD, as this will allow the EVO 75/150 to have sufficient ventilation.
