1.) What did you use to route your wires through on the backside? It looks like some kind of cable catch with 3M tape on the back.
2.) The majority of braided/sleeved cables there look to be from your PSU. I think those are from an AX1200 but did you also sleeve your other cables to match it? What kind of sleeving did you use if you did?
3.) Do you get any bulge on the non-windowed door because of the mass of clumped cables?
The third question could be asked of any 900D owner really. I seem to be having some door issues with my 900D. I have a slight bulge on the non-windowed door that I believe is due to some poor cable management on my part. Both my doors do not pop off when pressing the quick release now as well; I have to pry them off. I don't think they have popped off easily since a day or two after I started my build. Guessing I might have damage something on both sides.
I also noticed my window has a scratch on it and the paint chipped away on the bottom. I am not 100% sure if either of these are my fault but does Corsair cover this part under warranty or would I need to pay for a replacement?
