I was a little nervous about building inside a Hadron since so it seemed so many people complained about how tight it was and how hard it was to cable manage. Once I got it and started piecing it together I realized there is just so much room for activities. Cable managing was a breeze. Yes, cables are visible, it's a piece of electronic equipment, it has cables, but they are all out of the way and do not impede airflow which is really what I find important. I'm extremely happy with the tiny footprint of this case, it was exactly what I was looking for: the smallest possible case that could fit a powerhouse of a video editing machine.
The Basics: I swapped the case fans out to noctua ppc pwm 2000rpm fans and I changed the cpu cooler fans to nf-a9 pwm fans. With such a small case cooling could be an issue so I wanted to make sure I could address it with fans that could ramp up when needed but be as silent as possible when under low load. Some tweaking with speedfan and the fans now idle at the lowest possible speed before fully shutting off and slowly increase speed (sound) as needed depending on temps. I've had no temp issues with this setup even after a couple hours at full load. After a while at full load the cpu runs at around 65c and the gtx 980 runs at 75c, sound levels are reasonable with all fans running at around 1500rpm (No manual oc, only w/e stock oc the card and cpu run from the factory)
The clips for the fans on the cpu cooler do not clear the ram... all other points on these clips attach fine so I simply left the lower one that hits the ram unattached and tucked it out of the way. I've had no issues and the fans are not loose in any way.
For the wifi card I ripped the intel 7260 that came with the mobo used on my HTPC/NAS build since that box is wired to directly to the router. It worked like a charm. http://pcpartpicker.com/b/CnCypg
Future plans: I might add another SSD in raid 0 if they go on sale for kicks and add the evga dvd drive just to fill up the hole. There's not really much of anything I could think of doing to improve this pc. I'm very happy with it.
Overall this thing is a mini beast; It's handled anything I throw at it. Gaming across three monitors (5040x1050) is damn nice, and it's cut my video rendering time in half vs my old 8 physical core workstation. Only downside for me is the max 16gb of ram since I like using ramdisks for faster video editing/rendering. As it stands I have 3 monitors running off the video card and a tv running off onboard graphics... figured that would save some energy when I'm just watching a movie or so. I love this thing.
