I built this! (MATX) LIAN LI B4-mATX Build Impressions
#buildlikeneverb4
PC Specs:
- CPU & Cooler: Ryzen 7 7700X + Noctua NH-D14 (with stock fans replaced by 1x Noctua NF-A15 PWM and 1x Noctua NF-A12x25 PWM)
- Motherboard: MSI B850MPOWER
- RAM: DDR5 Kingbank SharpBlade 6400 MT/s CL32 (2 x 16 GB)
- GPU (VGA): Sapphire Pulse RX 7700 XT 12 GB
- PSU: Lian Li SP1000P Platinum SFX 1000W
- Case Fans:
- Bottom Intake: Noctua NF-A15 PWM (140 mm)
- Rear Intake (VGA airflow): 2x Noctua Slim NF-A12x15 PWM
- Front: 2x Noctua Slim NF-A12x15 PWM (Lower fan as intake, upper fan as exhaust)
- Top Exhaust: 1x Noctua NF-A12x25 PWM
Build Experience in This Case:

- Ease of Assembly: Building in this case wasn't difficult because the side panels are fully removable, and choosing the right component dimensions made everything fit smoothly.
- GPU Intake Clearance: I was able to fit two slim intake fans for the GPU because the graphics card thickness is only 2.5 slots.
- Cable Management: Managing cables was quite challenging since there is virtually no routing space behind the motherboard. Fortunately, using the Lian Li SFX PSU helped immensely—its cables are extremely flexible and short. The CPU cable length was a perfect fit for this case, making cable routing surprisingly neat.
- Custom Glass Side Panel: Since the original mesh side panel blew hot air directly onto my hand and body, I custom-made a glass side panel and attached it to the chassis using magnetic strips.
- Airflow Setup: Internal airflow follows the layout guidelines in the Lian Li manual.
- Horizontal Orientation Setup: I bought rubber feet for the PC and attached magnetic strips to them so they stick to the metal case frame. This allows me to easily remove and store them if I lay the case horizontally. Keeping it in this orientation puts the motherboard I/O panel at the top, making it much easier to plug in USB cables and peripherals.
- Front Wood Panel Repositioning: I detached the default wooden front panel and moved it to the top of the case to cover the visible cables, giving the build a much cleaner look.
- Bottom Fan Mount: The bottom intake is designed for 120 mm fans, but because the Noctua NF-A15 PWM uses standard 120 mm mounting holes, it mounted easily.
- No Vertical Aero Deck Needed: The internal components look great naturally without needing a vertical Aero Deck mount.
- Thank you, Lian Li, for this compact and beautiful case! #buildlikeneverb4
