Drilled some holes in the plates and fitted my connectors, very snug fit, but I forget the size of the bit used.
Me sizing them up within the NES, notice the back plate, the power connector is larger than the NES's original cut out, and the Right channel for audio is offset a little bit. Can't blame me....it wasn't precision....and marking it with a pencil on black plastic in low lighted conditions......
Dremel'd out the sides of the NES ports to fit the power connector and Right audio channel connector and it fits very snug.
Borrowed the wires from the original NES power switch to wire up the AV connectors. Used some standard plugs on the end to make a modular PC....so I can switch mobos if I find an upgraded Intel Atom mini itx board. Oh yes, lovely held up by a lot of Hot Glue, but seems quite sturdy. In the last picture, you see a black wire, which I used to jump the ground for audio from the Left Channel to the Right Channel, avoids tangled up cables in the enclosure.
Testing locations for the HDD, this corner seems nice, and thats why I left these 2 screw posts.
Dremel'd out the side of one of the screw posts to slide the HDD into. Then drilled a hole through the bottom....just one...hardly noticeable, to mount it in place. The Expansion slot on the NES, the portrusions that hold the clip on the bottom in place, also keeps the HDD from moving as well. Very snug fit. Also I put a thick paper like poster material on top of the HDD to prevent shorts from the bottom of the Mobo just in case.
More pictures to come.
