I am an IT guy and always looking for small form factor computers.  I pushed my customers to purchase these computers for over a year.  I've probably ordered at least 20 of these computers so I have a very broad diverse group of users with these computers.  I bought 6 for a client in Albuquerque. 2 of the 6 after 4 months would no longer boot and dead as a door knob.  I purchased 2 more for my clients in Dallas in the last 3 months and had one today do the same thing. These computers have a major issue with power. I haven't been able to take it apart and diagnose the issue but it's either a bad/faulty  power supply or motherboard.  So far out of the 20 I've purchased this will be my 5th that has died with no power within 3 to 6 months.  The sellers do not respond and there is no warranty.  Spend extra and get the Dell Micro series.  My clients are beyond pissed due to no warranty so i'm eating the cost.  I should have know after 2 went dead so quickly.
