There is no alternative to water cooling. It's in it's own category.
It'd be REALLY tough to fit in a good sized tubing water cooling kit in that mid tower man. Especially if you went with a weapon heatercore, as you've probably read they are 2 120mm fans on that thing, so it's pretty big.
You're already having a tough time with wires, don't count on trying to stuff even more things in that case and have it work out well.
Modding that case is about your only option.
I'd highly suggest nothing than a full tower especially if you wanted 1/2" tubing.
1/4" tubing is the smallest they got, but that kills performance and a weaponcore uses 5/8" barb which is slightly bigger than 1/2" tubing so those things aren't made for such tubes.
That arctic cooling looks to be nothing but air solutions
