If we assume the computer consumes 200 Watt in average, the electricity price would be something like 0,32 USD per kWh. So probably Germany, Denmark or Belgium.
The story looks faked all over the place. 30 TB? I have as much, and the storage price was maybe $600 last year.
In early 2018 an 8TB seagate drive cost ~$200 according to https://jcmit.net/diskprice.htm .
I'm also counting usable storage, not snapraid or anything like that. The reality is it's 39.12 TiB not counting SSD cache.

I also bought a pretty nice case that can store 10+ hard drives, and a PCIe sata adapter. I probably could have done it for cheaper, but that's not really a reason to call me a liar is it? Why would anyone fake this?
Also, OP included a Usenet subscription in their costs so they might not be torrenting at all.
