My Lian-Li 343B Case 3-loop Project - Initial Pump Testing

[Cascades]

Great idea on the pump mountings and Great Case Cascades, any idea if its possible to mount a pa120.3 on the top mount, and would it require cutting the top blowhole any bigger..

Yes, you would have to cut a much larger hole to mount any tripple-fan radiator in the top of the case.
