## Overview
The be quiet! Silent Base 802 Black (model SLT-BSE-802/BK) is a mid-tower PC case that strikes an excellent balance between noise damping and expandability. It features up to 10mm thick damping mats on the front and side panels, effectively absorbing internal component noise. The package includes both a standard solid front panel and a mesh airflow front panel, letting you tailor the case to your cooling or silence priorities.
Out of the box, the case comes with three Pure Wings 2 140mm fans (two front, one rear) spinning at 1000 RPM, providing adequate airflow with minimal noise. Two top covers are also included: a solid one for silence and a ventilated one for improved exhaust when using liquid cooling. This modular approach makes the Silent Base 802 highly versatile.
Motherboard support spans E-ATX (up to 305×277mm), ATX, Micro-ATX, and Mini-ITX. Maximum CPU cooler height is 185mm, and GPU length can reach 432mm, meaning even the largest air coolers and flagship graphics cards fit without clearance issues. The spacious interior also accommodates up to 360mm radiators in the top and 420mm in the front.

## Compatibility Guide
* Motherboard support: E-ATX (max 305×277mm), ATX, Micro-ATX, Mini-ITX
* CPU cooler clearance: 185mm (fits most large air coolers like Noctua NH-D15)
* GPU clearance: 432mm (accommodates even the longest RTX 4090 models)
* PSU clearance: 288mm (bottom mount, plenty of room for cable management)
* Storage: up to 7× 3.5-inch drives and 15× 2.5-inch drives
* Radiator support: front up to 420mm, top up to 360mm, rear 120/140mm
* Included fans: 2× 140mm front, 1× 140mm rear (Pure Wings 2, 1000 RPM, 3-pin DC)
* I/O ports: 1× USB 3.2 Gen.2 Type-C, 2× USB 3.2 Type-A, HD Audio, fan speed switch
Real-world pairing example: you can install an E-ATX motherboard, a Noctua NH-D15 CPU cooler, and an RTX 4090 simultaneously without any interference. Cable management space behind the motherboard tray is generous, though routing cables for an E-ATX board requires a bit more care.

## Product Info
The Silent Base 802 launched in November 2020 and sits in the mid-to-high-end segment of be quiet! 's case lineup. It is designed for users who prioritize silence but still want the flexibility to install high-end cooling and large components. The case ships with two front panel options (solid and mesh) and two top covers (solid and ventilated), allowing you to adapt the chassis to your specific build.
Warranty is 3 years from the manufacturer. The case is widely available through major retailers and online stores. Its market positioning is ideal for enthusiasts who want a quiet system without sacrificing expandability.

## Best Use Cases
* Silence-focused PC builds: The thick damping mats and included quiet fans make this case perfect for users who want a near-silent system. Use the solid front panel and top cover for maximum noise reduction.
* High-end gaming rigs: With support for 432mm GPUs and 360mm radiators, you can build a top-tier gaming PC with an RTX 4090 and a custom liquid cooling loop. Switch to the mesh front panel for better airflow under heavy loads.
* Creative workstations: E-ATX support and abundant drive bays (up to 7× 3.5-inch, 15× 2.5-inch) make this case suitable for content creators who need multiple SSDs/HDDs and a powerful GPU. The quiet operation helps maintain a focused work environment.
* First-time builders: The case is relatively easy to build in, with good cable management and tool-less drive mounts. However, its large dimensions (539×281×553mm) require a spacious desk or floor area.

## Things to Consider
* The case is large (539mm deep), so measure your desk or floor space before purchasing.
* The solid front panel restricts airflow; if you are running a high-TDP CPU and GPU, consider using the mesh panel for better cooling.
* When installing a 360mm radiator in the top, check clearance with tall RAM modules (e.g., Corsair Dominator) and motherboard VRM heatsinks.
* The included fans are 3-pin DC, not PWM. Ensure your motherboard supports DC fan control or use a separate fan controller.
* Competitors like the Fractal Design Define 7 and Corsair 4000D Airflow offer similar features at comparable prices. The Silent Base 802 stands out with its dual-panel system and thicker damping material.
## FAQ
Q: Will an E-ATX motherboard fit without covering cable routing holes?
A: Yes, up to 305×277mm E-ATX boards fit. However, some cable routing grommets may be partially blocked depending on the board's shape. Plan your cable routing accordingly.
Q: Can I install a 420mm radiator in the front?
A: Yes, the front supports radiators up to 420mm (3× 140mm). Make sure the radiator thickness does not interfere with the GPU length; with a 420mm radiator, maximum GPU length reduces slightly, but still accommodates most cards.
Q: Which front panel should I use for a Ryzen 9 7950X + RTX 4090 build?
A: For such
