OWC Helios FX 550W
Just found refurbished: https://eshop.macsales.com/item/OWC/HELFXRX580O/
Do they worth it?
Or Helios is worse than Sonnet?
@alexander_kim I cannot really comment regarding the Sonnet enclosure but my OWC Helios FX with RX 580 is working flawlessly to this day in macOS configuration. I have read that both the Sonnet and Helios FX enclosures are identical (or about) for the hardware side but are somewhat different regarding the firmware implementation.
Maybe some other members here can comment on this.
@alexander_kim I actually bought "Open Box" in new condition.
