Hey guys I need some advice before I buy a new case. I've been trying to find the most suitable upgrade to my NZXT H500i as I'm becoming more interested in doing a multi gpu setup for work and need more adequate cooling. The only problem is that I only have enough real-estate on the desk for an h500i or CoolerMaster SL600m. My initial thought is to go with the SL600m Black Edition since it allows for vertical gpu mounting of several cards and has a unique airflow design. Here's what I've been looking at, and you guys tell me what makes sense. I really to keep the case footprint as small as possible.

For Inspiration, really like the look of the side mounted fans:

Go for Phantek.

Pretty nice case. The chimney idea is just fine. What matters is will the case you chose do all the things you want to do. From cooling, to sound and even future possibilities. 
 
I looked at that CM (As my favorite all time until now was the Cooler Master Stacker 830) offerings pretty hard. Having just spent the last seven years with a Corsair Obsidian 700, I knew what was to big and what features I actually wanted/needed.
 
Ended up trying Phantek P600s and really like it. Price "Was not" a part of my search parameters...
