parts needed:
old nes console
itx motherboard (i used asrock qc5000 board)
itx power supply
harddrive (i used 1000gb)
1 40mm pwm fan
12v 10a adapter
2 nes to usb converters

Step 1: First Step, Clean Out Inside of Case.

Take out all of the original NES components. I cut all of the standoffs except for the 4 corners of the case. the standoffs can be reused by cutting and then gluing them back into the correct places for the mainboard and accessories.

Step 2: Cut Out Motherboard Hole and Glue in Backplate, Place Motherboard and Glue Standoffs

after cutting a hole with dremel and gluing in the backplate the old standoffs can be cut and glued into place to hold the board.

Step 3: Connect Original Controller Ports to Adapters by Soldering.

Step 4: Connect Power Supply, Fan and Ram Along With Harddrive.

in this step everything just needs to be connected. i used the old power button fronts, but used my own buttons due to space constraints.

Step 5: Boot Up and Install Windows. Then It Is Ready to Use.

Step 6: Inside Assembled Detail

    sorry for the real late reply. there are 2 easy options for the power button. you can either use the stock button assembly with the button modified so it doesnt stay in. or what i did is get a bag of 100 little buttons from china for $2 and glued them in place. either way works.

    I would like to have the power button act like a regular pc button and have the nes button stay in while powered and have the nes pc running like normal. Thanks in advance for any and all help

    kinda late but all you need to do is take off the metal pin on back of power button and bam! i did that to mine and kept the functioning power and reset buttons as you would on a pc . I even went a bit further and added a wireless remote starter that has a 100 foot range .

    That could be done. just would need to cut power to the existing power button, and use a microswitch at the end of the button stroke. That way the button would hit it for a moment and then rest not touching the switch.

    I personally think that if you are going for a real NES look you should remove that io shield and cut out holes for each of the ports. Or even better run extensions to the back that turn into ports and use them for just the cords you need.

    Still a really cool project though :)

    the fan has also been upgraded to a fractal design 40mm ultra quiet fan

    that is a good point and something i would consider if doing it again. my main goal was for it to look like stock from the front as the back already needed a fan hole.
