Who it fits

Key specs explained

Motherboard Support: EATX, ATX, Micro ATX, ITX

This chassis accepts a wide range of motherboard sizes, from small ITX to large EATX boards. You can install motherboards up to 305 by 330 millimeters. This flexibility allows you to use high-end enthusiast boards without worrying about physical fit. It is ideal for builders who want to mix and match components or upgrade to larger boards in the future.

Material: 0.8mm SPCC

The frame is built from 0.8mm SPCC steel. This thickness provides a sturdy structure that resists flexing when you install heavy components. It offers better rigidity than thinner frames, ensuring your motherboard stays aligned. The black sandblasted paint finish adds durability and a clean look. This material choice supports long-term stability for open-air builds.

Graphics Card Length: Not limited

There is no specified maximum length for your graphics card. You can install very large, high-end GPUs without worrying about clearance issues. This is crucial for modern cards that often exceed standard lengths. It gives you the freedom to choose the best performance card for your needs without structural constraints. This feature benefits enthusiasts using massive cooling solutions.

Power Supply Support: Standard ATX

The case accommodates standard ATX power supplies with dimensions up to 150 by 86 by 250 millimeters. This allows you to use common, widely available power units. Longer units up to 250 millimeters fit, giving you options for higher wattage or quieter fans. It ensures compatibility with most mainstream and enthusiast-grade power supplies on the market.

Design and Build Quality

The JOYJOM PC077 features an open-frame chassis constructed from 0.8mm SPCC steel. This material thickness provides a rigid structure for your components without the bulk of a fully enclosed case. The metal is finished with a black sandblasted paint, which offers a durable surface that resists scratches and fingerprints during frequent hardware changes. You get one open air PC case and necessary accessories in the package. The design prioritizes direct access to all internal parts, making cable management and component upgrades straightforward tasks.

According to the listing, the assembled dimensions measure 440 by 345 by 128 millimeters, or 17.3 by 13.6 by 5 inches. When you install a standard ATX power supply, the height increases to 160 millimeters, or 6.3 inches. The width remains 17.3 inches, and the depth is 13.6 inches. This compact footprint allows the test bench to fit on most standard desks or workbenches. The open layout ensures maximum airflow around your GPU and CPU, as there are no side panels to restrict air movement.

The chassis supports standard ATX power supplies with dimensions up to 150 by 86 by 250 millimeters. Storage options include space for two HDDs and two SSDs. The open frame design means you can install graphics cards of any length or width, provided they fit within the frame. This flexibility is ideal for builders who use large, high-end GPUs that might not fit in traditional enclosed cases. The practical layout supports a wide variety of component configurations.

Setup and everyday use

Setting up the JOYJOM PC077 involves assembling the open-frame chassis and mounting your components directly onto the steel frame. The package includes the case and necessary accessories for this process. You begin by installing your motherboard, which can be any size from ITX to EATX, provided it does not exceed 305 by 330 millimeters. The open design allows you to access mounting points easily without navigating around internal walls or drive cages. Next, you install your power supply. The frame supports standard ATX power supplies, which can vary in length from 140 to 250 millimeters. This flexibility ensures compatibility with most modern high-wattage units. You then attach your storage drives. The chassis provides space for two hard disk drives and two solid-state drives, keeping your data storage organized within the frame. Graphics card installation is straightforward, as the case places no limits on the length or width of your GPU. This is particularly useful for large, air-cooled cards that might not fit in enclosed cases. Once assembled, the unit measures 440 by 345 by 128 millimeters. If you install a longer power supply, the depth increases to 160 millimeters. Daily use benefits from the open-air design, which promotes maximum airflow and simplifies cable management. You can easily reach components for upgrades or troubleshooting without removing panels. The black sandblasted finish helps hide fingerprints and minor scuffs during regular handling.

Before You Buy This Bench

You need a separate desk or stand to hold this open frame. The assembled dimensions are 440 by 345 by 128 millimeters, or 17.32 by 13.58 by 5.0 inches. If you add a power supply, the height increases to 160 millimeters. Check your room for enough space. You must provide your own power supply. It fits standard ATX units up to 250 millimeters long. You also need to buy fans and drives separately. It holds two HDDs and two SSDs. The steel frame lacks dust protection. You should clean it regularly to prevent debris buildup. This setup suits builders who want maximum airflow and easy access. It differs from enclosed cases by exposing components to the environment. You sacrifice dust filtering for better cooling and simpler maintenance. Consider your workspace carefully before ordering.

Check before you buy

• Verify your desk can support the 440 by 345 millimeter base.
• Confirm your power supply fits within the 250 millimeter length limit.
• Ensure you have space for the 160 millimeter height with PSU.
• Plan for separate fan and drive purchases as none are included.
