Review on 🖥️ Mantiz MZ-03 Saturn Pro II EGPU - Thunderbolt 3 External GPU | MacOS/Windows Compatible | Intel Thunderbolt Certified | With SATA3 2.5 SSD/HDD, SD, USB 3.0, Gigabit LAN | Dual TB3 Chip for Enhanced GFX & Extra IO (Black) by Greg Bloom

This is a rugged unit with a simple sliding rail for easy card replacement, a full size ATX power supply (with 3x 8 pin connectors to support the new rtx 30xx series requirements) and 2x TB3 Controller so you can use it as a docking station without significantly impacting GPU performance. To top it off, the construction is solid and the finish is really well done (although I'm not a fan of the front decal and that suction cup is etched in there making it difficult to remove).
