Verdict
OWC Mercury Helios 3
6 / 10 Expert Rating
Solid basic Mac eGPU box, superseded by the Helios FX which OWC still actively sells.
PowerColor Devil Box
5 / 10 Expert Rating
A historically significant early Thunderbolt 3 eGPU box, but bare-bones even by the standards of its own era and long discontinued.
