This is a PC I built for my company. We needed a workhorse that some engineers could remote into to use a program called Pix4D mapper. Since the software uses all cores and available memory we decided to just go all out.
At first a normal job took over eight days. Now this pc finishes it in 23 hours.
CPU: we wanted as many cores as possible without going insane with the price (hence no dual xeon gold setup).
CPU Cooler: This system will be running 100% for hours on end. I needed a cooler that can handle whats basically a torture load.
Motherboard: Honestly any would work, I chose Asus for its reliability.
Memory: pix4d takes in millions of pictures taken by a drone, these pictures are stored in memory during the processing. They are about 10 MB per pic and a job can have hundreds of thousands. I've seen this use up to 80% of the 128GB.
Storage: Pix4d loves fast storage in it's compression and saving phase. the ssd is the primary with the 4TB HDD as an off load of jobs that may be needed to reference.
PSU: 1000W is more than what was needed however I wanted an 80+ Titanium and the extra give in wattage since it will be running at full load for long periods of time.
Video Card: Really any would do here, pix4d does use it in its last stage for ray cloud but it was recommended a gaming card and the 2070 was in a decent performance / price area.
Case: Now I specifically chose this for the EATX support and the air cooling support. With this large number of fan support, the cpu stays cool.
