Where the layers disagree ⚡
3 CONTRADICTIONS DETECTEDPRICE PERCEPTION: USER comments view the €4000 price tag as 'illegal' and a bad value compared to DIY, while VIDEO reviewers admit the price is high but justify it by the proprietary, space-saving engineering.
POWER SUPPLY ADEQUACY: USER comments specifically warn that the 600W power supply is dangerously under-spec'd for the i9 and 3080 Ti, a technical flaw not highlighted in the VIDEO reviews which focus on out-of-the-box performance.
LONG-TERM VIABILITY: While VIDEO reviewers praise the compact design, a USER who owned a previous generation (i160) warns that the proprietary AIO liquid cooler is not user-replaceable, and Corsair runs out of replacement parts, effectively bricking the machine eventually.
