Now, put the board back into the chasis.
The screws might not line up so easily, but you can manipulate them from the bottom through the tape one at a time until they fit.








Now go back and tighten the heatsinks down. If you still red ring, maybe it is unlevel or not tight enough. It doesn't take a lot of pressure. You only want it to be snug.


Then, I cut a window into the top of the case above the fan for intake.
If you also decide to put a fan, make sure it is intake and sucks air in.
