@Rich looks great! I double-side taped the IO ports too, but on the right. It's not super nice, but the Door is now close 100% of the time. Only thing that would be awesome, is a big metal Mesh fanguard large enough for the whole hole left by the 3 fan casing + integrating the IO ports in that, and than, only mount the Fans to that new front and mount that New front to the Drop-In braket behind in 4 corners. That will look more "built for the case", specially on the L4000 that doesn't have a 3rd fan shroud...
I finally went to install my L4000 case in a client's Server room, it's so quiet in the home now, i didn't remember how quiet it was Prior to have a miner in the living room ! :O
Something like that :

That would be nice, mounting the 3 fans to that plate + the IO ports (i add it in red on the right). Everything could be screwed to that plate, and then the plate screw in the drop-in bracket, on the normally fan holder.
If you need a ginny pig to test it out on a L4000, I'm your guy hehe
