There are a number of valid engineering reasons for thermal dissipation why you don't want to overload the heat producing things in a 1U server beyond what it was designed for. This article doesn't mention at all what the max TDP of each gpu is, which makes me suspicious. Or things like max tdp of cpus (such as when running a prime number calculatio multi core stress benchmark to load them to 100%) combined with total wattage of GPUs. If you have never built an x86-64 1U dual socket server from discrete whitebox components (chassis, power supply, 12x13 size motherboard, etc) this is harder to intuitively understand. I would recommend that people who want four powerful GPUs in something they own themselves to look at more conventional sized server chassis, 3U to 4U in height, or tower format if it doesn't need to be in a datacenter cabinet somewhere.
