Ok, so the main thing that stands out is your motherboard. It neither supports SATA 6.0Gb/s hard drives nor DDR3/2000MHz RAM. Either upgrade your motherboard to one that supports these devices or drop down to a SATA 3.0Gb/s hard drive and DDR3/1600 or /1333 RAM. Also, do you really have a need for an $14 HDMI to HDMI-Mini printer cable (especially when Amazon.com has them for 44 cents)?
Regardless, I went with these components; matching as best I could and came up with a similar build on Newegg for $820 shipped ($790 after MIRs) or $780 shipped ($740 after MIRs) using a 640GB SATA 3.0Gb/s and 4GB (2x2GB) DDR3/1333 RAM. Of course, shopping at Newegg, you have to build it yourself and you are your own tech support.
Personally, I'd go with doing more research on building your own system and part compatibility. Whatever site you went to for that build should never have allowed you to make the selections you did with that motherboard. To me, that just shows a poor attitude towards customer service. They know full well you'll send that system right back to them when you can't get it to boot up.
