I'd guess that the reason PC Part Picker could not confirm compatibility with your cooler is because Raidmax does not mention the maximum cooler height in its published specifications.
I just spent 10 minutes on Google. All I found is that the width of the case is 8.86 inches, which doesn't tell you anything useful.
I did find some negative comments about Raidmax cases generally, complaining about lack of dust filters and poor cable management.
I would not use that case UNLESS I was willing to take a chance that the cooler would fit---assuming you can't find confirmation with Google.
The Hyper Evo cooler is 159 MM in height. That is 6.3 inches.
