The black rolling cart has a manually adjustable height range, compatible with most computer cases on the market. You can customize the height from 25.38' to 32.68' to adjust the distance between the PC tower and the top panel. This can speed up the heat dissipation process and improve the overall performance of your computer. Mobile computer cart has a versatile design that allows it to be used not only as a storage unit for your PC tower, but also as a temporary workbench. It features a spacious desktop equipped with wheels that have brakes, allowing you to move the stand to your bedside or sofa and use it as a temporary workspace for your laptop. Computer cart also comes with a convenient pegboard on the back, which provides additional storage space for plugs, headphones, keyboards, and other items. To help you make the most of this feature, we provide pegboard accessories as a gift, allowing you to customize the storage layout to suit your needs.
