Not sure why this doesn’t exist. I don’t need 12TB of storage. When I had a Google account I never even crossed 15GB. 1TB should be plenty for myself and my family. I want to use NVMe since it is quieter and smaller. 2230 drives would be ideal. But I want 1 boot drive and 2 x storage drives in RAID. I guess I could potentially just have 2xNVMe and have the boot partition in RAID also? Bonus points if I can use it as a wireless router also.
Not sure how you came to that conclusion, but even in places with very cheap electricity, it does not even come close to your claimed $0.375 per month. At 25 W you would obviously consume about 18 kWh per month. Assuming $0.10/kWh you’d pay $1.80/month. In Europe you can easily pay $0.30/kWh, so you would already pay more than $5 per month or $60 per year.
Just used cpubenchmark.net.
