first of all i am a fan of this site. i use this site for long time but never created an account so here i am today. ok now let get down to business. which one has better airflow and cooling case? the blackhawk ultra got more space and fans, is that mean better cooling system? or the famous Haf X. the blackhawk ultra is at its cheapest price so far
both cases are great!but there are some better cases for similar price tag,
3-inwin dragon rider
5-Azza hurricane 2000
7-Thermaltake chaser MK-I
and few more and if you prefer mid towers than 550D,650D and 600t are great mid towers.
and it's not case that is loud,it's the fans.throw quality fans in any case and BAM! you have a silent case.
but if you don't want to with anything else then HAF X is definitely a better choice.
