Hello fellow lefty
I would go for the Dark Base Pro 900, a little on the expensive side but the build quality and modularity are amazing, the things you can do with that case are incredible. Plus it comes with be quiet!'s Silent Wings 3 fans, and surprisingly good sound dampening foam, which make the computer virtually silent. I always want cases to last for years, especially if I find one I really like, so to me, it justifies the price.
