Energy I have no idea - but my guess based on the PSU is: very low. Total initial cost was a little above 1k€ though I did pick a very silent, high quality case as well as a very OK CPU (aiming with it both to perform transcoding with Jellyfish with no lags for sure and to add new services to the NAS - torrent downloading, hosting dedicated servers for games, etc.). This also includes a 256GB nvme drive for the OS (debian). I also wanted a small form factor so I had to get a good mini-ITX motherboard, and holy shit are those more expensive than their ATX counterparts (makes sense mind you: higher components density + lower demand), to the point where I slightly regretted it.
Anyway: price could go lower if you were willing to compromise on some of the above (just a larger ATX case and a slightly less beefy CPU would help by at least 200€; hunting for deals would allow you to shave much more if building it over weeks/months), though admittedly the main cost was still the four good quality 8TB drives IIRC, in RAID5 - with weekly emails reassuring me of the states of the array as well as an immediate alert in case of any suggestion of failure. Also added a SATA extension card and plan to add two more drives to it (the case supports it fine), raising the storage to either 32TB or 40TB depending on whether or not a spare is kept ready. Also pretty sure by removing some of the useless shit (SSD slots and the like) from that same case, at least one more drive could fit fine.
Mine is an old gaming pc bought off a friend (core i5 gen 4) with a bunch of drives in snapraid/mergerfs. That gets rid of the storage overhead and power consumption of real raid. The pc cost about $100 and the drives were a little over $80 apiece many years ago.
It costs about three dollars to run a gaming pc with ten disks 24/7 for a month. Once the video card came out it really wasn’t too consumptive. Even as a seed of its idling most of the time!
how much does that cost (both purchase price and monthly energy cost)?
