Lancool
Fractal Design
The Antec is the mini version, not full size, not really fair comparison, are you using mATX build? If so go for the Antec, used to have original P180 and it was very good/excellent, plus if you are mATX then the mini would presumably take up less space (cant be bothered to check)
Havent used either of the other two but from reading around the fractals are popular choice/well regarded so if full size build go for that I guess
I love my Lancool, great for air cooling.
But the Fractal looking more sleek.
Either way, i think youll be delighted with both
Have you looked at youtube reviews??
