I would not buy anything else than top-rated laptop from Lenovo, Dell, or HP. These companies make shoddy laptops as well, but their top-rated models are reliable and have powerful colling system made of two connected fans. Thinkpads have additional advantage of protective roll cage. When ThinkPad laptop drops on the floor, its roll cage absorbs impact energy.
This laptop model (GoBOXX SLM 15) is ultra-thin, which means that it cannot survive drop on the floor and is difficult to repair. If I were you, I would call tech support of this company and ask them about the heat rating of their cooling system. Heat rating means how many watts of heat can the cooling system dissipate. Some modern GPUs are so powerful that they make as much heat as the CPUs. If the cooling system is mediocre, the laptop will run at its maximum speed for a few seconds, and then it will throttle to half the maximum speed because it overheats.
If you buy laptop that is not mass-produced, do not be surprized if spare parts are not available three years later.
