I recently moved the components of an existing server into a new SC-316 case. I ordered a Seasonic SS-600H2U power supply to replace the somewhat elderly Seasonic ATX power supply that was in the old case.

Unfortunately, when I turned on the power supply for the first time, I was greeted with an angry vacuum cleaner sound that suggested bad fan bearings.

See the following video:

I filed a support request with ServerCase, sent them the video, and they wordlessly sent me a new power supply without even asking for the old one back. Thanks very much!
