## What reviewers say

**O11 Dynamic EVO** — Only one whitelisted source survived verification: Tom's Hardware's hands-on of the exact O11 Dynamic EVO. It is explicitly a hands-on build rather than a full lab review (the author states they don't have cooling and acoustic numbers), and it praises the case's near-endless modularity while flagging its enormous, likely floor-bound footprint, inconvenient bottom-mounted I/O, the lack of any included fans, and how quickly cost escalates once you add kits. The originally-cited TechPowerUp lab review was dropped because the fetched page returned only the review's introduction and none of its conclusion quotes were present in the text. (1 sourced review.)

**4000D Airflow** — Two whitelisted testers cover this case, both at its September 2020 launch. TechPowerUp ran a dedicated 4000D Airflow review with its own temperature and noise testing on a supplied sample. Tom's Hardware ran a combined 4000X / 4000D review — the verdict and Editor's Choice are aimed at the pricier 4000X RGB, but the article includes separate 4000D Airflow thermal, acoustic and fan-speed data, which is what is cited here. Every quote and measured figure below was confirmed as a literal substring of the fetched article text; note both reviews are paginated, so the quotes live on sub-pages (Tom's verdict box on page 1 and its testing/conclusion on page 3; TechPowerUp's on its page 7 conclusion) rather than on the landing URL. Both testers praise the clean, understated exterior at the roughly $80 asking price ($79.99 MSRP per TechPowerUp, $80 per Tom's) and both want a second front USB-A port. Only Tom's produced measured cooling and acoustic results. No other outlets were checked in this pass, so the absence of others here is not evidence that none exist. (2 sourced reviews.)
