Great case

This is my second custom build now and this case was so much easier to work with than my previous one. Plenty of space, I've not done too bad with wire management but I'm not expert in that field and not the best person to ask on if it's a great case for wire management. The case has a overwhelming amount of custom features which I've barely got into, I was a big fan of how you can take the back plate out which the mother board attaches to, it made assembly much easier.
I'm really happy with the way it looks now. I recommend this case.

Awesome pc case.

Upgraded from corsair 450 D to the Be quite dark base 900 pro. Temps before on the 450 D were very good with my Asus Gtx 1080 ti strix oc & i5 4590k @ 4.5 Ghz. Was slightly sceptical of the front intake fans being behind the front door, but the temps have stayed the same which is testament to the design off the 900 pro." Positive points" Easy to build in. Plenty off room for watercooling, Very quite, Good cable management. case is built like a tank , very classy. Only one minor gripe is the lack off a Psu cover which would finish off the inside.

Photos don't do it justice

Just upgraded from silent base 800 to this.
I have the 280mm be quiet cooler.
Temps hover low 60s whilst gaming fit CPU (1.3v 6700k) and 74 max for GPU (overclocked 1.075v gtx msi 1070 gaming x
I have an additional intake silent wings 3 in bottom.
Stunning performance with looks to die for.
