I have a bitcoin miner I purchased 5 months ago from B and C Tech Solutions. I want to sale my server but I don't know what type it is? The salesman said it is custom made and wouldn't give me any specs on it. How can I identify this server with no outward tags?
Usually devices have a sticker on the back or bottom. It tells you serial number, make and product number. You can also try to make a clear picture of the device and run it through Google reverse image search.
