King of Cable Management

This build is my first try with 12V and discrete GPU.
The K39 case housing the hardware is going to sit next to the TV set, not far from the couch.
I'm indeed in need of an HTPC, so why not make one with which I can play games?
But with such a small case and the ITX size GPU restriction, this is going to be a Light Gaming HTPC only.
The star of the show is of course the M2426 PDCB from @Thehack , which is going to deal with the 'always On' problem.
Indeed, when attached directly to a 12V PSU, a GPU is constantly fed with 12V even when the system is powered down.
But thanks to the M2426 and its 5Vsb and PS_ON wires acting as an On/Off remote, the MeanWell PSU stops providing 12V when the motherboard is shut down.
Here come the actual parts (*second hand), subject to be improved in the future:
- K39 black case (196*117*218mm 5L)
- MeanWell RPC-500-12-C 500W 12v AC-DC PSU (130*86*42mm)
- M2426 200W 12V PDCB
* Asus Z97I-Plus
* Intel i5 5765C CPU
- ID_Cooling IS-60 EVO (92mm bottom fan only)
* 2x 8GB DDR3
- 1TB SSD
* GTX 1660Ti
Electrically speaking, this is the plan:
The K39 case is designed for a Flex ATX PSU, thus the corresponding aperture at its back:
And that's what I am going to put in instead:
A C14 inlet, along with a fuse and a switch.
As there was some place left, I have also added a reset switch with an HDD LED.
The frame is made out of a 1mm aluminium plate that was lying around. It is a bit thin but works fine if you insert the power cable gently.
To prevent touching some live wires at its back, I've also made a little cover out of a plastic box and black tape for good measure.
