This article covers 静かに! Pure Base 500 ATX ミディタワー PCケース.

Overview

The be quiet! Pure Base 500 (model BGW34) is a mid-tower ATX case that prioritizes silence without sacrificing basic cooling versatility. It arrives with two pre-installed Pure Wings 2 140mm fans and noise-dampening mats on the front, side, and top panels, making it one of the quietest options in the budget-to-mid-range segment. A standout feature is the interchangeable top cover. The solid version with insulation foam keeps noise down, while the ventilated mesh top maximizes airflow for high-performance builds. This flexibility lets builders tailor the case to their cooling and noise preferences. The case supports front radiators up to 360mm and top radiators up to 240mm, so liquid cooling setups are well accommodated. At a price point typically under ¥10,000 (around $70-90), the Pure Base 500 offers excellent value for silent PC enthusiasts. It's especially attractive for first-time builders who want a calm, quiet system without spending a fortune on premium components.

Compatibility Guide

Motherboard Support: ATX, Micro-ATX, Mini-ITX. Standard layout with room for full-size boards. PSU Mounting: ATX power supply mounted at the top. Cable management space behind the motherboard tray is adequate but not generous; modular PSUs are recommended for cleaner builds. CPU Cooler Height: Up to 190mm clearance, which fits nearly all flagship air coolers like the Noctua NH-D15 or be quiet! Dark Rock Pro 4. GPU Length: No official maximum stated, but real-world builds confirm cards up to around 300mm fit easily; longer cards (330mm+) may require removing the front fan or using short radiators. * Radiator Support: Front: 120/140/240/280/360mm; Top: 120/140/240mm; Rear: 120mm. Note that top clearance with thicker radiators can interfere with tall RAM or VRM heatsinks.

Best Use Cases

Budget Silent PC Builder: If you want a near-silent system for office work, HTPC, or light gaming, the Pure Base 500 delivers out of the box. The included fans and damping mats handle noise effectively without extra cost. Mid-Range Gaming Rig: Pair it with a Ryzen 5 or Core i5 and an RTX 4060-class GPU. The case provides enough airflow for these components while staying quiet under load. Good for gamers who hate fan noise. AIO Liquid Cooling First-Timer: The front 360mm support makes it easy to install a 360mm AIO; just remember to flip the top cover to the mesh panel for better exhaust. This combination can tame a high-TDP CPU with minimal noise. Who Should Skip It: Enthusiasts building with top-tier, high-heat components (e.g., Intel Core i9-13900K + RTX 4090) will likely find the airflow restrictive. In such cases, the Pure Base 500DX with a mesh front panel is a better choice. Also, those needing lots of internal 3.5” drive bays won’t be satisfied by the limited two-drive bracket.

Things to Consider

The main trade-off with this case is silence vs. airflow. The solid top cover and foam damping reduce noise but also restrict exhaust, raising internal temperatures under sustained load. Switching to the mesh top cover helps but increases noise slightly. Cable management can be tricky due to the top-mounted PSU and limited rear space. Thick PSU cables may bulge the side panel. Full-modular PSUs and careful routing are essential for a clean look. The case lacks a built-in fan controller; if you plan to install additional fans (it can hold up to 5x 140mm), you will need to rely on motherboard headers or aftermarket controllers. Also, the glass side panel is tinted dark, which hides non-RGB builds but gives a premium look to illuminated components. ## FAQ
Q: Can I install a 360mm AIO in the front? A: Yes, the front bracket supports 360mm radiators. However, with a typical 30mm thick radiator + 25mm fans, the GPU maximum length reduces to around 300mm. Check your card dimensions before committing. Q: How quiet is this case with the included fans? A: Very quiet at stock speeds (around 800-1000 RPM). Under moderate system load, the noise floor stays below 25 dBA. If you run the fans at full speed, the sound is still subdued thanks to the damping material. Q: Can I reuse my existing PSU and motherboard from an older build? A: As long as the PSU is standard ATX and the motherboard is ATX or smaller, yes. Note that the case uses a top-mounted PSU design, so long cables may need careful routing. Also, the motherboard tray cutout for backplate access is generous, so swapping coolers is conve
