Verdict
Sonnet eGFX Breakaway Box 550
6 / 10 Expert Rating
A solid early Sonnet box, but the 650 offers more headroom for little extra cost.
StarTech.com StarTech Thunderbolt 3 PCIe Expansion Chassis
5.5 / 10 Expert Rating
A capable, inexpensive DIY PCIe expansion box, but its limited power delivery and lack of laptop charging make it a compromise pick next to purpose-built gaming eGPU enclosures.
