ALAMENGDA DIY Pc Test Bench vs JOYJOM Open Air PC Case

Design and build quality

Both the ALAMENGDA DIY Pc Test Bench and the JOYJOM Open Air PC Case are designed to provide an open-air environment for computer hardware testing and assembly. These chassis eliminate the constraints of traditional enclosed cases, allowing for maximum airflow and easy access to components during benchmarking or troubleshooting. The primary design philosophy for both units centers on functionality and ease of access rather than aesthetic enclosure. Users can quickly mount motherboards and test configurations without the hassle of side panels or cable management constraints typical in closed systems. This open-frame approach is ideal for enthusiasts who frequently swap hardware or need to monitor component thermals directly.

Material and paint finish

Construction durability is a key factor for test benches that may be moved frequently or subjected to repeated assembly cycles. The ALAMENGDA DIY Pc Test Bench utilizes a high-quality 0.8mm SPCC steel plate, ensuring structural rigidity. The surface is treated with baked black sand grain paint, which provides a textured finish that can resist minor scratches and fingerprints. Similarly, the JOYJOM Open Air PC Case is made of high-quality 0.8mm SPCC material coated with black sandblasted paint. Both manufacturers have chosen identical material thicknesses, suggesting comparable weight and sturdiness. The difference lies primarily in the description of the paint texture, with one specifying a sand grain finish and the other a sandblasted coating, though both aim for a matte black industrial look.

Motherboard compatibility

Compatibility with various form factors is essential for a versatile test bench. The ALAMENGDA DIY Pc Test Bench supports motherboards within 305245mm, covering standard ATX, Micro ATX, and ITX specifications. This range ensures that most consumer-grade motherboards can be mounted securely. The JOYJOM Open Air PC Case offers wide compatibility as well, supporting ATX, Micro ATX, and ITX motherboards with a maximum size of 305245mm (12*9.6inch). There is no functional difference in motherboard support between the two units, as both accommodate the same maximum dimensions and form factors. Users selecting either product can expect to fit standard desktop boards without issue.

Graphics card clearance

One of the main advantages of open-air cases is the removal of length restrictions for graphics cards. The ALAMENGDA DIY Pc Test Bench states that the number of graphics cards supported depends on the motherboard, but the length and width of graphics cards are not limited by the chassis itself. This allows for the installation of oversized GPUs or multi-GPU configurations limited only by the motherboard slots. The JOYJOM Open Air PC Case mirrors this capability, noting that the length and width of the graphics card are not limited. For users with large aftermarket coolers or extended PCB designs, both options provide the necessary physical space to operate without obstruction.

Power supply support

Adequate space for the power supply unit (PSU) is critical for stability. The ALAMENGDA DIY Pc Test Bench supports standard ATX power supplies with a reference size of 150mm86mm(140-250)mm. This covers the majority of ATX PSU form factors available on the market. The JOYJOM Open Air PC Case supports standard ATX power supplies with dimensions of 150 x 86 x (140250)MM, also providing imperial conversions of 5.9x3.39x5.59.8 inch. Both units accommodate the same range of power supply depths, ensuring compatibility with standard modular and non-modular units. The JOYJOM listing provides slightly more detail by including imperial measurements, which may assist users accustomed to inches.

Storage drive options

Storage mounting capabilities can differentiate test benches intended for temporary testing versus semi-permanent setups. The ALAMENGDA DIY Pc Test Bench features do not explicitly mention support for hard drives or SSDs in the provided specifications. This suggests it may be focused purely on core component testing without dedicated drive bays. In contrast, the JOYJOM Open Air PC Case explicitly supports 1pcs HDD and SSD. This addition allows users to install boot drives or storage volumes directly onto the test bench, making it more suitable for extended testing periods where operating system installation is required without external enclosures.

Physical dimensions

Knowing the overall footprint of the chassis helps in planning workspace layout. The ALAMENGDA DIY Pc Test Bench does not provide specific overall product dimensions in the available feature list, listing only the supported motherboard size. The JOYJOM Open Air PC Case provides detailed dimensions, stating the product size after assembly is 440x265x128mm (17.32x10.43x5.0 inch). It further notes that dimensions after the power supply is installed increase to 440x265x160mm (17.32x10.43x6.3inch). This transparency from JOYJOM allows users to verify fitment on their desks or workbenches more accurately than the ALAMENGDA option.

Price and value

Cost is often the deciding factor when specifications are closely matched. The ALAMENGDA DIY Pc Test Bench is priced at $15.69, making it the more affordable option of the two. The JOYJOM Open Air PC Case is listed at $15.99, a marginal increase of thirty cents. While the ALAMENGDA DIY Pc Test Bench wins on pure price, the JOYJOM Open Air PC Case justifies the slight premium with included accessories and explicit storage support. For users who need drive mounting and dimension certainty, the JOYJOM Open Air PC Case offers better overall value despite the higher sticker price. However, for basic motherboard testing without storage needs, the ALAMENGDA DIY Pc Test Bench remains a cost-effective choice.
