I've been looking at the HAF series, and the stryker series (can't find the trooper in stock anywhere) but the stryker looks cheap to me, and the HAF X/932 etc, seem the best way to go but I'm unsure. Trying to find the absolute best case I can. I want the best. just looking for suggestions, everything I have read has been inconclusive.
