My goal was to wade back into casual gaming with a capable 1080p gaming computer in a small form factor, and this was easily achieved with this build.


-To make the graphics card fit next to the HDPLEX 400W AC-DC, I had to de-pin the Skywire GPU cable and heat shrink each wire to make ultra low-profile cables. I had never done anything with cables before and it was a little bit daunting, but I used these links to help me and it turned out to be quite easy and fun (I ignored the first heat shrink wrap suggestion in the second link):

-Cut and fit Velcro to the front panel of the S4 Mini so it would come through the cut-outs in the chassis to allow Velcro mounting of the HDPLEX HiFi DC-ATX.

-The 40mm fan included with the HDPLEX 400W AC-DC would not fit on the back side of the chassis with the included C6 connector, so I Velcro'ed one edge of it to a wall on the front side of the chassis instead with a little space for it to pull air from the front and blow through the AC-DC out the back. I don't think I've ever heard it turn on as this system pulls very little power, and frankly it's probably unnecessary but I liked having it just in case.

-I used extra rubber and foam from a ping pong paddle to cut out a spacer for the C6 connector. I had to get two longer M2.5 screws as well as a nut and washer to mount it correctly. There might have been space for the C6 connector to fit flush but it seemed a little too tight for my liking and preferred having a little extra room with minimal effort.

All the folks on the SFF Forum, the NFC Discord Channel, and especially Josh from NFC Systems were extremely helpful. I hope this guide assists another enthusiast as these people assisted me.

Did that cpu cooler fit without modification? Is there any interference with the vrm heatsink?

How are CPU temps with the Ryzen 5 3600 and the Noctua NH-L9a cooler?

CPU package temps are around 62C or so with default everything and the low noise adapter on. I'm quite fine with this personally but I wouldn't be surprised if you could do a lot better with tweaks.

Exactly how much space is between the HDPLEX AC-DC and the power connector of the GPU? I'm looking at very near this exact build, but I'm trying to avoid the de-pinning process with something like this adapter.

Hi there!

I actually tried that exact same adapter and it just would not fit no matter how much I tried to cram it in. I was going to throw my hands up in the air until Josh at NFC encouraged me to give the de-pinning a shot. It ended up taking only about half an hour or so and it was actually kinda fun. There is basically no other way for these components to fit as the spacing is probably something like 1mm, much too small for even the sleekest adapters.

I'm loving this build! Best of luck and enjoy! Cheers.
