Or or or stop being an anal asshole about it and just leave the topic alone. Ever thought of that? Huh? It's just a fucking firepole they don't need one.
As people said before me posting. It's never a good idea to get prebuilts for gaming. It's a terrible idea in fact. You can expect the max of 2 FPS out of that machine on 4K. But the parts list that Chasem121 posted is a good enough machine to run 3x1080P monitors in fact that would be the recommended setup in your case.
Don't get the 900D it's over used and over hyped. It's a terrible case for airflow too. Get something like a Define S for airflow or just stick with the R5 if you want something more functional.
What if you could cram a 960 or something better in there? Make a second PC in another NES box or a Xbone with power far better than that of the consoles.
Yea i'm following that other thread where you made it for your wife. I still think it looks better without a side panel window. It just makes it flow better without the window.
