Edit 30/01/2024 after 3 months it broke. It's not a good solution if you want to move your unit on top of it. It's better to choose the CPB3. It's economical. It does the job but you don't feel it sturdy like the CPB3. Even though the second one costs 3 euros more per hour as I write this, I believe it's worth it for the additional protection on the right and left sides, as well as its greater thickness to better support the weight of the unit.

I initially considered the groove on this specific stand as an advantage to allow better airflow for the power supply, but now that I have it in my hands, I feel that it is its disadvantage, its weak point. Since the wheels are after the groove, it bends under the weight at that point, as all the weight is supported by the strips on the right and left. Because my case is not long, I still chose to place the groove at the back of the case, not that the phenomenon doesn't occur that way, but at least the center of gravity is better distributed and I feel less risk of the stand opening in two. I should note that the case weighs just under 12 kilograms and that the stand moves relatively easily. It remains stationary without activating the brakes on the wheels, so I can move it at any time. It has 2 wheels with brakes and 2 without. Its dimensions are 45x23x1.5 cm (LxWxH). With the wheels, its height is around 6.5cm. Assembly is very easy, you just attach the 4 wheels and it's ready.
