Well crikey, could it be there's an update to be had? There is indeed! Time for some soldering methinks...
So, rejigging the case layout to accommodate the 360 radiator means there's no space to use the stock front panel connectors. The original plan was to veroboard some switches and LEDs together, but about 18 months ago (I know, I know) I thought "let's just go all-in with this project and make up everything custom I can". So out with the veroboard, in with some custom PCB design
If you're looking at doing PCBs, I strongly recommend
EasyEDA. The online editor is just incredible for creating your circuit schematics, hooking in real manufacturing parts and generating PCB layouts with proper footprints. EasyEDA is in the same group as LCSC for components and JLCPCB for PCB manufacturing, so you have a one-stop-shop to design, make and populate your custom bits.
4-pin fan headers and SATA power I sourced elsewhere, but the EasyEDA editor allows you to create your own component footprints too, so I grabbed the Molex specs and drew up the missing parts.
And here we are! (Excuse the potato phone pictures, the room is very gloomy. Tidied up as best I can)
No extra charge for black board, no extra charge for simmer board thickness, and 5 boards for very little money if you stay within a 100x100mm footprint. Winner.
I know you're not going to see them once installed, but if Asus can put a ROG logo on their Thor PSU heatsinks then I can sure as hell brand my PCBs
Combination front panel interface and PWM fan splitter
The rightmost fan header connects up to the Maximus VIII Impact's fan extension control board with the other 3 for the ML120s. There is also a 2-pin header on the very right edge sharing the 12V input for the fans which I'll be using for a tiny LED strip. Fortunately the fan extension control board is actively powered so I don't have to worry that 3 LED fans and a 12V LED strip will burn a motherboard header
All laid out...
...with a pair of tiny holders for the 1.8mm LEDs, also designed and printed by moi.
4-way 12V splitter board, SATA powered
1mm thick PCB rather than 1.6mm as it's mounted to the back of the hard drive plate, so there's only 8mm gap until the motherboard. The odd shape is to wrap around some large surface components on the back of the motherboard.
Made me chuckle that JLCPCB threw in a magnifying glass as their token gift because that SATA power has 15 pins at 1.27mm pitch! My eyes don't work that small.
So let's do this!
