OriginPC, iBuyPowerPC, CyberPowerPC all offer prebuilt solutions... just be ready to pay for it. If you want to learn how to build yourself, I recommend getting a nice cup of coffee and watching
this series of YouTube videos (part 1 and part 2). For selecting your parts, PCPartPicker.com is a great resource, as is Logicalincrements.
With all that said, the actual act of building a PC is NOT hard. IMO choosing the right parts to make the PC building experience "not hard" is "the hard part". Choosing quality parts with favorable customer reviews will make your life a million times easier. This is what makes PCPartPicker invaluable.
