My current build, I'm clearly completely unable to do this myself. I thought i did good... I was wrong. Is it salvageable?

###Build Help/Ready:

Have you read the sidebar and rules? (Please do)

Yes

What is your intended use for this build? The more details the better.

This is my day-to-day computer. Internet, email, Netflix, Steam, That kinda stuff. If I get really randy, I might put Vectorworks on it one day.

If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)

Decent game settings for Steam games (Batman Arkham Somethingorother, Left4Dead, The Witness, maybe Minecraft with my son). Diablo is I feel frisky. Flash type games is more likely (newgrounds style).

What is your budget (ballpark is okay)?

under $800

In what country are you purchasing your parts?

USA

Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).

Here is my current Build. I bought this computer about a year ago. I fear it's... awful? Is it even fixable?
