The Spectacular Flagship of ITX: Jonsplus i100 Pro
In the world of SFF (Small Form Factor) cases, “modular” is often a buzzword, but for the Jonsplus i100 Pro, it is a way of life. Jonsbo’s enthusiast-focused sub-brand, Jonsplus, created the i100 Pro to solve the “big hardware in a small box” dilemma. The result is a spectacular silver monolith that offers an unprecedented level of internal flexibility. Whether you want to showcase your GPU via a vertical riser or build a traditional air-cooled powerhouse, the Jonsplus i100 Pro adapts to your vision, all while looking like a piece of high-end audio equipment.
Modular Interior: Three Layouts in One
The Jonsplus i100 Pro is unique because it allows you to choose your internal architecture:
-
Vertical GPU Layout (Sandwich): Perfect for showcasing your graphics card through the tempered glass panel while using an AIO for the CPU.
-
Horizontal GPU Layout (Classic): Allows for the installation of massive tower air coolers (up to 166mm), turning this into a mini-workstation.
-
Reverse Horizontal Layout: Optimized for specific airflow configurations. This level of customization is spectacular, ensuring that the Jonsplus i100 Pro remains relevant even as your hardware preferences change over time.
Premium Craftsmanship and Materials
The aesthetic of the Jonsplus i100 Pro is defined by its materials. The exterior panels are made from a 3.0mm thick aluminum-magnesium alloy, featuring a beautiful brushed silver finish that resists fingerprints and exudes luxury. The side panels are constructed from 4.0mm tempered glass, providing a spectacular view of your components. Every intake is protected by ultra-fine mesh filters, ensuring your high-end hardware stays as clean as the day you installed it.
Spectacular Cooling Capacity
Small cases usually struggle with 300W+ components, but the Jonsplus i100 Pro is built for the heat of modern gaming. It is one of the few Mini-ITX cases on the market that supports a 360mm radiator in the top. This allows you to cool even the most power-hungry processors from Intel and AMD without thermal throttling.
-
Fan Support: You can install up to six 120mm fans throughout the chassis.
-
Vertical Airflow: The “bottom-to-top” airflow design ensures that hot air is naturally exhausted, keeping the internal ambient temperature spectacularly low for an ITX system.
No Compromise on GPU or PSU
The Jonsplus i100 Pro ignores the typical ITX limitations.
-
GPU Clearance: It supports graphics cards up to 373mm in length. Whether you have a massive RTX 4090 or a high-end Radeon card, it will fit comfortably inside this frame.
-
Power Supply Versatility: While it is optimized for SFX and SFX-L units, the Jonsplus i100 Pro can also accommodate standard ATX power supplies up to 175mm (depending on the layout). This gives you an incredible range of options when choosing your wattage overhead.
The Detail is in the Design
Jonsplus spent a significant amount of time on the “quality of life” features. The case features a hidden cable management area that makes it spectacularly easy to achieve a clean look, even with the glass side panels. The front I/O is modern and minimalist, featuring a USB 3.2 Gen 2 Type-C port for lightning-fast data transfer and a combined audio jack.
Storage and Maintenance
Despite its focus on airflow and big GPUs, the Jonsplus i100 Pro doesn’t ignore storage. It features a versatile mounting system that can support up to one 3.5″ HDD and two 2.5″ SSDs. For maintenance, all panels—including the top, bottom, and front—are designed for easy removal, making it a spectacular case to work in for both first-time SFF builders and veteran enthusiasts.
Final Verdict
The Jonsplus i100 Pro in Silver is the definitive choice for the builder who wants a boutique, high-end PC that looks at home on a designer desk. It offers the spectacular flexibility of three different internal layouts combined with the cooling capacity of a full-sized mid-tower. If you want the ultimate flagship ITX experience with premium aluminum construction and 360mm AIO support, the Jonsplus i100 Pro is the undisputed king of its category.
