Open Frame ATX Test Bench

The ALAMENGDA open frame chassis uses .8 mm SPCC steel with a baked black sand-grain finish. It accepts ATX, Micro ATX and ITX motherboards up to 305 by 245 mm and a standard ATX power supply. One 3.5 inch bay and one 2.5 inch bay are provided for storage. The frame weighs 1.0 kg and measures 440 by 265 by 128 mm without the power supply fitted.

Unrestricted GPU And Dual Drive Support

Graphics card length and width are not limited by the frame, so any card the motherboard can physically accommodate will fit. The single 3.5 inch and 2.5 inch bays let builders install one hard drive and one SSD for a compact test or server configuration. No side panels or windows are included, keeping airflow completely open around the components.

Fixed PSU Depth And EATX Exclusion

The power supply mounting area follows the standard ATX reference size of 150 by 86 by 140 to 250 mm, so longer units will not fit. Motherboards larger than 305 by 245 mm such as EATX are not supported on this model. Builders needing more than one drive or a wider board must choose a different chassis.

Questions about this item

Will the 0.8 mm SPCC steel frame need any upkeep over time?

The black sand-grain paint finish resists corrosion, so the frame itself requires no scheduled maintenance.

What is the first dimensional limit reached when installing a long graphics card?

Card length and width are unrestricted; the motherboard's PCIe slot spacing is the practical limit.

How much heat builds up inside the open frame when the system runs continuously?

With no side panels, airflow is unrestricted, so component heat dissipates directly into the room without case-internal buildup.
