I can't show you a photo pluged in the printer, because I have replaced all the electronics, but as you can see in the photos, it had been using for a while and worked perfectly.
Supports are only needed for the rears, not in the vent conduct.
Version 1, goes together, and version 3 goes with the adapter.
The fan adapter cover, I am not sure if it is me or it actually only fits in one way, check it, anyway, it had been designed with minimal tolerance so, if you need or want to, you can sand the edge.
Also as you can see in the photo, I were using it with a 60mm fan, so i removed the 4 screws supports, that's completly optional, i did to prevent any posible problem which shouldnt happen, but just in case.
If you feel any vibrations (I didn't) you can add more screws and it should dissapear.
I am not completly sure if a 80mm fan would fit in the case, specially because of the height, I used this model with a 6010 (60mm x 10mm) fan.
