JONSBO has introduced the D33, a new Micro-ATX PC case designed to offer broad hardware compatibility within a mid-size footprint. The chassis is available in black and white color options, with both variants priced the same.
The case measures 455 × 238.2 × 368.4 mm, resulting in a total volume of around 40 liters. The internal layout adopts a front-mounted power supply position, allowing for improved space utilization and cable routing. The design supports standard Micro-ATX and Mini-ITX motherboards, including rear-connector M-ATX models, while providing 51mm of cable management clearance behind the motherboard tray.
Despite its compact classification, the D33 offers compatibility with high-end components commonly used in gaming and workstation systems. The chassis supports graphics cards up to 435mm in length, enabling installation of large triple-fan GPUs. Power supply compatibility includes ATX and SFX units up to 160mm in height, offering flexibility depending on build requirements.
For air cooling configurations, the case supports CPU coolers with heights of up to 172mm. Storage options include two drive bays compatible with both 3.5-inch HDDs and 2.5-inch SSDs, covering basic storage needs without occupying excessive internal space.
Cooling support is a major aspect of the D33 design. The chassis allows installation of up to nine fans across multiple mounting locations, enabling users to configure airflow depending on system requirements.
Fan support includes:
- Front panel: 2 × 120mm or 140mm fans (depending on power supply configuration)
- Bottom panel: 3 × 120mm fans
- Top panel: 3 × 120mm fans via removable metal bracket
- Rear panel: 1 × 120mm fan
The top mounting bracket also supports radiators up to 360mm, making the chassis compatible with larger all-in-one liquid cooling solutions.
The D33 combines a relatively compact 40-liter size with support for large GPUs and multi-fan cooling layouts. The front-mounted PSU configuration helps free internal space while maintaining compatibility with standard components. With support for rear-connector motherboards and flexible cooling options, the chassis is positioned for users building modern Micro-ATX systems with high-performance hardware.
