The Jonsbo BO400 VP is built around an aluminum frame and a wide glass-focused design that puts the PC hardware in full view. The case has a large internal layout, support for full-size components, and several mounting areas for builders planning an advanced custom PC.
The BO400 VP supports Mini-ITX, Micro-ATX, and ATX motherboards. Its dimensions are 474 × 311 × 489 mm, while the case weighs 12.9 kg.
Jonsbo builds the frame with 12 aluminum profile pillars and eight die-cast corner pieces. The hollow aluminum profiles are 2 mm thick, giving the case a different construction from the usual steel-frame design.
At the front is a 6 mm CNC-machined aluminum panel with an anodized brushed finish. The lighting section can connect to a 5V ARGB header for synchronized lighting.
The case comes with a metal top cover. Jonsbo provides a glass top panel for users who prefer a more open look, creating a three-sided glass view around the installed hardware.
Graphics cards up to 435 mm long can fit inside the BO400 VP. CPU air coolers can reach 173 mm in height, while ATX PS2 power supplies up to 200 mm long are supported.
The case has eight expansion slots. Jonsbo lists support for up to four 3.5-inch drives and two 2.5-inch drives in its product information.
Cooling hardware gets dedicated space across three sides of the chassis. The top, bottom, and side can each accommodate a radiator up to 360 mm long.
For air cooling, the top and bottom can each hold three 120 mm fans or two 140 mm fans. The side supports three 120 mm fans, while the rear has space for one 120 mm fan. The total capacity reaches 10 fans.
Jonsbo lists 76 mm of space beside the motherboard for a radiator installation. The case further supports a sandwich-style layout with up to 45 mm of fan thickness on the cable-management side.
The BO400 VP supports vertical graphics card installation through Jonsbo’s A50 PCIe 5.0 aluminum GPU mounting bracket. Buyers should check the exact package contents when purchasing the case and bracket.
The front I/O panel has two USB-A 3.2 Gen 1 ports and one USB-C 3.2 Gen 2 port. Power and reset buttons are present alongside the audio connections.
The Jonsbo BO400 VP is listed in China for 1,999 yuan (Approx $300). Its design is aimed at builders who want an aluminum case with wide hardware visibility, room for long graphics cards, and multiple large radiator mounting positions.
Jonsbo has not confirmed official pricing or availability for other markets.
