Replaced the power supply this morning, thanks to Velocity Tech Solutions in Minnesota's same day delivery, and the server is back up and running.
 Server was running fine for almost a month since it's last power down.. Last night I powered off the unit then unplugged it re rearrange some power cables and clean up the area.. After a couple hours, I plugged the unit back in and hit the power button and nothing!  So I reseated the power cable, and tried again.. Still nothing..  I got out a multimeter and check the female side on the power cord with a reading of 118v.  So I opened the case and peaked inside.. confirmed most of the cables and memory.  Tried again and still nothing.. So I gave up a bit and thought maybe it just needs to sit plugged in awhile.. Came back today and tried, hit the power button and until is still completely dead.. No light flashes, no fans.. Acts as if it is just it's not even plugged in..  I am assuming a faulty power supply at this point.. However, I am hoping there is a few other things I could test or try..   This server is much loved and would hate to lose it. However, I am unsure if worth investing $100 for a used power supply at this point.
