Buying this was a mistake... I wanted to gift my Son a PC for Christmas and looked more at price, CPU and RAM than the hidden details.This is a new PC design with the 300 watt ATX12VO (+12 volts only) power supply... so new, that you can't find an upgrade (the LITEON Power supply in it is "custom").  You cannot install an (industry standard and widely available) ATX12V power supply (the new form factor is smaller, the install screw holes don't match, the motherboard has a separate 6 pin and 4 pin connector instead of the usual 24 pin single connector, ...).  The new power supply provides only +12v (that's right... -12v, +5v, ... are gone) the motherboard now has to provide any other required voltages.  In addition, the Motherboard needs to provide connectors for HD, SSD, etc power (that's right... the power supply provides no drive power connectors).  This guy comes with 1 drive power cable (plugged on the motherboard, unused and tie wrapped to the internal wire harness) and 1 SATA cable (loose).  So, you can add 1 drive.If that isn't already a show stopper...Although you get a PCI-E slot, you can't plug in a graphics adapter because 1) there is no 6 pin power connector for the card 2) the bus can't supply the necessary power (even a low power card require 75 watts - that is a lot to pull through the tiny PCI buss connections) 3) The bios setting for using a plug in graphics adapter is greyed out... that's right... you can't tell it not to use the onboard graphics.Bottom line... If you are buying a PC for Granny to surf the net and write letters in Word... this is probably an ok PC to buy, otherwise, don't waste your time or money.The price on this PC should have been no more than $400.
