SPEC-Alpha is the worst of the three, only front, top and rear mounts with 120mm all around.
330R is better than SPEC-Alpha since it supports 140mm also. But again, only front, top and rear mounts.
The best would be 230T since it has 1x 120/140mm bottom intake while supporting 140mm on top as well. 120mm is at front and rear
