I've been testing Openmediavault for the past little while in preparation for a new NAS and I'm liking it. As with any opensource OS if there are problems you're going to need to jump into a CLI to fix the issue. Their forum is also less elitist than FreeNAS so if you need help they can usually offer it.
 
If you want an even more user friendly server you can take a look at amahi. I've never tried them, but it looks fairly simple, I just didn't like their paid model for something that I couldn't even really test beforehand

I used crossfire r9 290's - spacing is a must...
 
ULPS disables the second card at idle, it is literally turned off... so no extra noise at idle.
 
power supply - I ran mine on a good quality 750watt psu - this was borderline acceptable, I wasn't willing to push the core voltages at all.
 
support/microstutter: this is the kicker... I had terrible microstutter in Alien isolation and CS:GO - I had flickering headlights and 10 fps in menus on Grid Autosport, Farcry 3 was unplayable and Civ 5 wouldn't even launch... this was with the 14.4/14.7/14.9 driver releases... each was a little better but not perfect... AC4 was a bit poor as well
 
but when a game worked well... like Tomb Raider or Crysis 3 maaaaan it was prime, 60 fps flat @ 4k... at least 25% more performance than my gtx980.
 
That said... one of my cards was a reference card. it was loud and hot... my case was a mATX so it was tiny... the heat coming out the back of the case was intense lol.
 
TLDR;
For me it was too hit and miss with what games would work and what wouldn't, I also had issues with ULPS and had to reinstall windows twice getting AMD drivers to update. I decided a single card it the way to go and that AMD was not for me.

I would suggest setting the static IP address on the modem instead. So (if you can) I'd say undo what you did following that video (but if you can't, or rather wouldn't, I can try to solve the server issue).
 
All you need is the MAC address of the computer, and then in the menu that you posted (the reserve new IP address section), you need to enter the MAC address, IP address you want for it, and the hostname (I'm doubtful this needs to be the real hostname of the device, so put whatever in here, like "Home Server"), and everything should be all hunky-dory.

You can set a static IP in freenas see video below:

I have my VPN, 2.4GHz + 5GHz, UPnP disabled, and my chromecast works just fine...if that list was the solution to everything I should have a non-functional chromecast...but I don't
 
Anyways, The problem is most likely related to your encryption method, and passkey mode. WPA2 w/ TKIP+AES is what I use. I would also choose channel 6 or channel 11.
