Rosewill Helium NAS Max: Strengths & Caveats
✔ Advantages
- Massive storage expansion supporting up to 11 x 3.5-inch HDDs and 2 x 2.5-inch SSDs
- Turnkey cooling setup with four pre-installed 140mm PWM fans and front mesh ventilation
- Broad hardware compatibility including BTF back-connect motherboards and up to 420mm GPU clearance
- Modern front I/O featuring a dedicated USB 3.2 Type-C port
✖ Documented Caveats
- Tempered glass side panel favors desktop aesthetics over acoustic dampening panels standard in server closets
- Fully populating eleven mechanical hard drives substantially increases chassis weight and cable congestion
Lian Li B4-mATX: Strengths & Caveats
✔ Advantages
- Dense 21.3-liter dual-orientation enclosure supporting both horizontal and vertical placement
- Generous clearance for up to 358mm GPUs and 162mm tall CPU air coolers
- Comprehensive ventilation with full mesh panels and two included 120mm slim PWM fans
- Supports up to a 360mm liquid cooling radiator when configured with an SFX power supply
✖ Documented Caveats
- Installing a 360mm radiator mandates an SFX power supply instead of standard ATX
- ATX power supply compatibility is constrained to a maximum depth of 140mm
