I remixed this thing to fit my Anet A8 which has the "stiffi" style frame brace. I had to cut a section out on the side of the case and lid due to the lower support of the frame brace.
I also opened up the hole for the 80mm fan so there is no restricted air flow. I added a fan cover from the power supply cover.
As you can also see in the photo's I had to cut about 6mm off the end of the heat sink on the mosfet as it was preventing the cover from installing correctly. This shouldn't be an issue as the size of the heat sink is overkill for this printer and heat bed.
