Verdict
Plugable Thunderbolt 5 AI eGPU Enclosure & Dock
7 / 10 Expert Rating
A genuinely differentiated, well-specced Thunderbolt 5 eGPU box for local-AI GPU hosting, but it's brand new, Windows-only, and still awaiting independent benchmarking — treat the manufacturer's numbers as a starting point, not a verified ceiling.
