Hey all,
Just a note on the ‘no ARGB option’ in the ‘cons’ section. The cooler uses Cooler Master Mobius 120P (note the P) fans. These fans actually have an ARGB variant, see coolermaster.com/en-global/products/mobius-120p-argb/
I recently bought one, and easily swapped out the front-facing fan with an ARGB one, using non-ARGB one on the exhaust. You just need to carefully take off the grey face panel. They are really good fans.
