Request: Selection Suggestions

Budget:
<4000: desktop computer only

Expectations:
I expect to upgrade or go with an SLI in 3-4 years. While I currently am only using one monitor (will be updating to an 24 inch , 1080p monitor soon), I am also considering to expand to dual monitors.

Usage:
I will primarily am using this computer to play current gen and upcoming games on high or ultra settings. Games I play are: Dragon Age: Inquisition, Starcraft II, Battlefield 4, Titanfall, Guild Wars 2, and upcoming shooters, RTS, and MMOs. I will surf the web frequently, with plenty of tabs and windows up. Lastly, I will watch a lot of movies and videos.

Special Needs:
I want a compact chasis without compromising on space inside for additional upgrades in the future. I'd like it to be not too heavy as I sometimes LAN with friends if that makes a difference. I want it to be quiet enough so that I can't hear it when I have headphones on (non-noise isolating and volume is at low, non-deafening levels).

Notes:
I browsed around the config forum to try to tailor it to my tastes. However, as I don't actually have much technical knowledge outside of what I've read I would like someone to provide some feedback. Anything on the the compatibility and necessity of my selection and if there is something better within my budget. I don't plan on using any additional peripherals beyond my current corded gaming keyboard and mouse, headphones, and mic.

Thank you kindly in advance.

Thank you for the welcome and the feedback, bpratt. I've adjusted per your suggestions and will look into the chassis. I do love the aesthetic look of the Apollo though so I might keep it, especially after a cursory glance at the available options.
