The PCIe slot bracket can be rotated 90 degrees for vertical GPU installation (riser cable sold separately). The Pure Base 501 DX Black strikes a solid balance between expandability and silence, making it a strong choice for gamers, creative users, and anyone building a quiet yet capable system.

Product Info

Positioned below be quiet!'s Dark Base flagship series, it targets mainstream builders who want good airflow and low noise without a premium price tag. Dimensions: 231mm (W) x 450mm (D) x 463mm (H). Weight: approximately 7.8 kg. Construction is steel with a black finish. The front I/O panel includes 1x USB 3.2 Gen 2 Type-C, 2x USB 3.2 Type-A, and combined HD audio jack.

Best Use Cases

  • First-time PC builders: The roomy interior and straightforward layout make assembly easy. Clearance for large GPUs and coolers future-proofs the build. - Silence-focused users: With three PWM fans and noise-dampening design, this case runs quietly even under moderate load. Suitable for HTPC or office builds where fan noise must be minimal. - RGB lighting enthusiasts: The built-in ARGB strips can be controlled via the case button or synced with the motherboard. Users who want a clean, illuminated build without buying extra accessories will appreciate this.

Things to Consider

The mesh front panel requires regular dust cleaning. Built-in dust filters on the bottom and lower front are removable, but maintenance is needed more often than with solid panels. The 178mm CPU cooler limit is just enough for large dual-tower coolers like Noctua NH-D15, but check exact dimensions before purchase. Vertical GPU mounting requires a separate riser cable not included. Competitors in the same price range include the Fractal Design Define 7 Compact and Corsair 4000D Airflow. The Pure Base 501 DX Black offers a strong balance of airflow, silence, and included ARGB lighting, but buyers should compare against these alternatives based on their specific preferences for noise vs. airflow.
