How our engineering team was able to make up this architecture and design. There are nine ten and all the customer benefits that come from that including customer manageability refurbished router ease of access and all the thermal and powerful benefits we specifically place the hard drives the memory and the fans and CPUs in locations to achieve best-in-class goals and all that Dominic described. some of the other medieval Triton so looking at the architecture of the r9 talking about what which is really driven by thermal requirements so we need fresh air and led to the memory and processors so looking at the memory riser the memory sits directly above the processors this allows us to do is get fresh air into them into the memory fresh air into the processors to minimize the amount of airflow needed to cool these components so the memory isn't preheating the processors and the processor isn't preheating the m...
