GMKTec G3 SATA SSD addon with Fan

This is a small addon to GMKTec G3 that allows fitting 2.5'' SATA SSD and Fan on top to cool said SSD and the original Nvme and memory.

I used it with M2 SATA to SATA adapter below:

EDIT:

M2 Sata Adapter Converter | M2 Ngff Sata 7pin Adapter | M2 Sata Adapter Cable - M2 Sata - Aliexpress

Link doesn't work anymore, but the adapter looks similar to this one:

As M2 SATA connector inside is shorter than 2280 size (adapter size), I need to cut out small part of original semitransparent plastic part inside the case (case didn't lose any functionality in this part). Then SATA adapter was still on top of USB ports, so I used a little insulation tape on it just in case to prevent any potential shorts with adapter. In this setup it was fitted in a stable position. 

Printed addon has a cutout for SATA and power cable from adapter. Connecting it from outside allows for quick change of drives. Fitting everything inside was a little to tight fit for my liking :)

Fan is powered by USB to 4 pin adapter:

I made this addon, because my G3 was my NVR and I wanted to fit SATA disk nicely ;) I used NVME to host Windows 11 IoT with BlueIris. In place of the original WIFI card, I installed M2 Coral for AI analysis. As for SSD, I'm using Micron 5300 MAX 960 GB, stores around 2 weeks worth of videos from 6 cameras, and with my average writing of 30GB of videos per day, it will last me for 700 years ;)

Using 120mm Fan on top at low speed lowered slightly CPU temperatures and significantly NVME  (from near 100 C to 65 C) and SSD (from near 50 C to 35 C) temperatures.
