Got mine a couple hours ago. The only problem I had was I have a lot of old IP address on my modem from all the S1's and it grabed one of those so I had to check a couple before I found the right one. Running great so far! Noise is not as bad as I was exspecting but have a couple of ideas to try. ( have it in my basement and can hear it some from upstairs )
If you get more of them check out the S5 manual. Bitmain now has minerlink at www.minerlink.com. It will make finding them on your network much easier. But be patient. These take longer to boot up / show up on a network than the S3 or S1.
