This is an upside-down/inverted case where the motherboard is hanging from the case’s ceiling. There's nothing on the case's floor but dark black glass which reflects all the components above.
I was inspired by reflections in RTX technology and thought it'd be cool to build a rig that reflected light. It was quite a challenge to fit all the listed components in while maintaining clean aesthetics. The cables, radiator and power supply are all in the top chamber. All the components hang from the motherboard upside-down fixed securely by reinforcement to the case.
There is plenty of airflow with four intake fans and one exhaust plus the 2x120mm GamerStorm radiator/fans combo. I currently have the 9900K overclocked to 5ghz (all cores) with sustained max temps at max 80deg with ambient of 24deg Celsius.
There's also tons of storage with seven drives! Plus still another x4 PCIe slot to use.
Overall very happy with the outcome, hope you like it too.
