Tek Everything has released a new build-video featuring the NFC S4T with a Ryzen 5700G APU. The video shows the complete build along with thermal testing using a Noctua NH-L9a. This should give anyone considering this case a good look at the base build.
I can hear your mind asking the question “what do you mean base build?”.
The Not From Concentrate Skyreach S4 Tiny starts at only 3.3L. However, you can stack multiple cases together and expand the design to add expansion. Essentially, the case can expand to whatever size you want, however 7L will easily get you a system with an ITX sized GPU built in.

In the meantime, be sure to check out both the Tek Everything video, and their website.
