## What reviewers say

**H7 Flow (2024)** — One whitelisted tester's quotes survived verification. Tom's Hardware tested this exact model (H7 Flow 2024) and rates it a solid, airflow-focused mid-tower that is very easy to build in, with room for up to 10 fans and large radiators, but flags conservative styling, no dust filters, and the need to add your own fans to exploit the improved airflow. A TechPowerUp review of the same case was dropped because only its intro page could be fetched, so none of its conclusion quotes could be verified. Numeric temp and noise results sit in image charts, so no measured values could be extracted verbatim. (1 sourced review.)

**AIR 903 MAX** — Two hands-on testers (Tom's Hardware, TechPowerUp) both rate the Air 903 Max a standout budget airflow case, praising strong thermals and its sub-$80 price with four fans and a PWM/ARGB hub. Tom's measured a fairly loud 48.5 dBA peak and flagged PWM noise oscillation at 40-49%; TPU's gripes were cosmetic and cable-routing (blue USB-A ports, missing grommets). No RTINGS/PCMag coverage found. (1 sourced review.)
