Phanteks EX5: Strengths & Caveats
✔ Advantages
- Compartmentalized multi-chamber architecture isolates heat zones and optimizes direct airflow corridors to key hardware.
- Pre-installed S25-120 mm rear mainboard fan actively cools VRM, memory, and M.2 storage zones.
- High-speed front-panel connectivity features a dedicated 20Gbps USB Type-C port.
- Integrated server-style GPU mounting bracket prevents graphics card sag on cards up to 358 mm.
✖ Documented Caveats
- GPU thickness clearance decreases to 2.6 slots if the motherboard designates Slot 3 as the primary PCIe slot.
- Base chassis requires user-supplied cooling hardware, lacking bundled intake fans or CPU radiator equipment.
Lian Li B4-mATX Vertical AeroDeck: Strengths & Caveats
✔ Advantages
- Expands cooling capacity with support for up to three 120 mm or two 140 mm intake fans
- Delivers direct, high-volume airflow toward the graphics card in vertical orientation
- Premium construction pairing rigid 4.0 mm steel with tempered glass and wood accents
- Includes a magnetic PVC dust filter for intake protection against ambient dust
✖ Documented Caveats
- Requires relocating the chassis front I/O panel during installation
- Strictly restricted to vertical setups on the Lian Li B4-mATX chassis
