Ok, so first off I completely agree a lot of these choices are excessive, but I've got $3000 of funds from work for a PC refresh, and its "use it or lose it." I'm setting aside $500 for the monitor, so that leaves roughly $2500 for the machine itself. I want the best I can get for $2500, that will last me as long as possible.
What it will be for: Physics simulations for work (which will want 32GB of RAM), VR/Gaming for home (hence the 9900k and RTX2080)
For the Motherboard, I've read that the VRM leaves a lot to be desired with overclocking. Would the Asus ROG STRIX Z390-E Gaming or the Gigabyte Aorus Master be better options for a Motherboard?
For the AIO, I was also considering the Corsair H115i Pro RGB. I've read that while the Kraken looks cooler, the CAM software is garbage. Thoughts on what I should get?
For the SSD, I've decided that NVMe is not worth the premium for my usage. Is there any benefit to M.2 (non-NVMe) vs SATA with the 860 Evo? I guess I just don't need a SATA cable with the M.2 approach? Any concerns with fitting the M.2 SSD and the RTX2080?
Would there be a better version/brand of the RTX 2080 for me to go with?
Any issues with the H500i case and these beastly components? I know the 9900k runs hot, and the H500i has a solid front wall, so I didn't know if airflow and cooling would be an issue.
