Who it fits

Key specs explained for JOYJOM

Case Type: Open Frame

This design lacks side panels and a top cover, leaving components fully exposed. You get maximum airflow for cooling without needing complex fan layouts. It is ideal for bench testing or short builds where you need to access parts quickly. However, it offers no dust protection or sound dampening, so it suits clean, controlled environments rather than dusty or noisy rooms.

Motherboard Support: ATX, Micro ATX, ITX

The frame accommodates three standard form factors, including the largest ATX boards up to 305x245mm. This flexibility lets you use almost any consumer motherboard without compatibility worries. You can upgrade from a small ITX board to a full ATX model later without buying a new case. This wide support makes the frame a versatile choice for various DIY projects.

Graphics Card: No length or width limits

Unlike enclosed cases that restrict GPU size, this open frame allows any graphics card dimensions. You can install large, heavy, or triple-fan cards without worrying about clearance issues. This is crucial for high-end gaming or workstation builds where size is not a constraint. It simplifies assembly and future upgrades since you do not need to measure internal depths carefully.

Power Supply: Standard ATX

The case supports standard ATX power supplies with dimensions up to 150x86x250mm. This ensures compatibility with most common desktop PSUs on the market. You can use standard modular or non-modular units without modification. The open design helps PSU fans intake cool air directly, potentially improving efficiency. Just ensure your specific PSU model fits within the stated maximum depth.

Build Quality and Physical Layout

The chassis is constructed from 0.8mm SPCC steel, finished with a black sandblasted coat. This material choice provides a rigid skeleton for your components while keeping the overall weight manageable. The listing states the unit weighs 2.54 pounds. This light frame makes it easy to move for bench testing or to reconfigure your workspace. You do not need to worry about the case adding significant mass to your desk setup.

Dimensions are compact for an open frame design. The assembled case measures 440x265x128mm. Once you install an ATX power supply, the depth increases to 160mm. The width is 10.4 inches, and the height is 6.3 inches. This footprint leaves plenty of room around the motherboard for cable management and component access. The open layout ensures you can reach every part without removing panels.

Support covers ATX, Micro ATX, and ITX boards up to 305x245mm. Graphics card length and width are unrestricted, allowing you to use large cards without clearance issues. The case supports one standard ATX power supply and one HDD or SSD. Controls are not integrated into the frame itself. You will need to connect power switches directly to the motherboard. This setup is best for users who prioritize airflow and easy access over a finished, enclosed look.

Setup And Daily Use Guide

Setting up this open frame chassis is a straightforward process that relies on your existing components rather than complex assembly. The listing includes the main frame and necessary accessories, so you will need to source your own motherboard, power supply, and storage devices. Installation begins with mounting your ATX, Micro ATX, or ITX motherboard to the steel base. The frame accommodates boards up to 305 by 245 millimeters, giving you flexibility in choosing your core platform. Next, you install a standard ATX power supply. The unit supports power supplies measuring between 140 and 250 millimeters in length, allowing you to use efficient or high-wattage units without space constraints. You can also mount one hard drive or solid-state drive, providing basic local storage options. Graphics card selection is entirely up to you, as the open design places no limits on the length or width of your GPU. This lack of restriction is crucial for users building with large, modern video cards. Daily use involves placing the frame on a stable, flat surface. The final dimensions with the power supply installed are 440 by 265 by 160 millimeters. This footprint fits comfortably on most desks. The 0.8mm SPCC steel construction ensures the frame remains rigid during operation. You benefit from immediate access to all components for troubleshooting or upgrades. The black sandblasted finish helps resist fingerprints and minor scratches during routine handling. This setup is ideal for environments where you need quick access to hardware for testing or maintenance.

What You Need to Know

You will need to source your own components, as this frame only includes the chassis and basic accessories. Ensure your ATX power supply fits the specified dimensions of 150 x 86 x (140~250)mm. Graphics card length is unrestricted, which offers flexibility for large GPUs. You must also account for the extra height when installing the power supply, raising the total depth to 160mm. This open design requires careful cable management to keep your workspace tidy. Unlike enclosed cases, there are no side panels to contain dust, so you may need to clean the interior more frequently. This unit suits bench testing and temporary setups better than permanent home theater PCs. It sits alongside other open frames by prioritizing accessibility over protection. If you need a sturdy base for diagnostics, this steel frame provides a reliable platform. However, if you require a quiet, dust-free environment for daily use, consider an enclosed option with proper filtration.

Check before you buy

• Verify your ATX power supply fits the 150x86x(140-250)mm dimension.
• Check if your motherboard is ATX, Micro ATX, or ITX.
• Ensure your workspace can handle 160mm depth with PSU installed.
• Plan for frequent cleaning due to lack of dust panels.
