after a few mails with their support i found out that i can also pay in cash at their office. to me it doesn't seem to be a scam to be honest. suspicious yes, but can't say something for sure. don't know how you people are so sure. tomorrow i'm going to their office and pay in person cause they are just a few miles away.
i'll be back with details.
All you order IS the case. The DS412+ is just an enclosure, it doesn't come with hard drives ( I own one). Wouldn't it be easier to just build the case instead of buying this and having to strip out the drive bays and SATA ports, plus the 2+Ghz CPU, proprietary Synology OS and package system USB/eSATA and 2x RJ45 ports are a little overkill for a miner don't you think? It isn't very cost effective as a case.
I hate you.
