Desktop mATX chassis Jonsbo D200 Tårn — black, without power supply

Jonsbo D200 Tårn is a mid-tower mATX desktop chassis in black supplied without a power supply. Designed for micro-ATX motherboards, this compact case provides organized internal mounting space for storage drives, expansion cards and multiple cooling configurations while keeping a conservative exterior. The absence of an included PSU allows builders to select a power supply that matches their performance and efficiency requirements.

Advantages

The Jonsbo D200 Tårn offers a space-efficient layout that supports common desktop components in a smaller footprint than full-tower cases. Its straightforward internal arrangement simplifies component installation and cable routing. The black finish and restrained design make the chassis suitable for both gaming and professional environments. Because the case is supplied without a power supply, users can fit a PSU of their choice to optimize wattage, modular cabling and cooling.

Suitable for

• Micro-ATX gaming rigs with discrete graphics cards
• Home and office PCs where a compact footprint is preferred
• Custom builds requiring a specific PSU choice or modular cabling
• Systems prioritizing flexible cooling configurations and storage options

Key specifications

• Form factor compatibility: micro-ATX (mATX)
• Chassis type: mid-tower
• Color: black
• Power supply: not included (user-supplied)
• Drive bays: internal mounting space for 2.5" and 3.5" drives (configurable)
• Expansion slots: support for standard PCI(e) expansion cards suitable for mATX layouts
• Cooling support: space for multiple fans and standard air-cooling solutions; clearance for typical CPU coolers and rear/side fan mounts
• Front and rear panel access: standard I/O cutouts and fittings for cables and connectors

How to use

Install a compatible micro-ATX motherboard onto the standoffs, then mount storage drives into the designated internal bays using the appropriate screws or tool-free mechanism if provided. Fit a user-chosen power supply into the PSU compartment and connect main power cables to the motherboard and components. Insert expansion cards into the available PCI slots and attach cooling fans or CPU coolers within the supported clearance limits. Route cables along the case interior to maintain airflow and secure panels back in place after verifying all connections.

Usage recommendations

Choose a power supply with the appropriate form factor, wattage and connector set for your components; modular or semi-modular PSUs can simplify cable management in this mid-tower mATX chassis. Plan component layout and cooling before assembly to ensure adequate airflow and to avoid interference with larger graphics cards or tall CPU coolers.
