Challenging 500~ PC Build! (I'm from Puerto Rico)

What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.

Fallout 4 ect ect, all the games !

What is your maximum budget before rebates/shipping/taxes?

500ish can go above if it's worth it

When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

Today if I can

What, exactly, do you need included in the budget? (Tower/OS/monitor/keyboard/mouse/etc)

Only the tower I have everything else

Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?

Puerto Rico

If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.

I'll reuse monitor/keyboard/moues ect

Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?

Unsure

Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)

Not really

Do you have any specific case preferences (Size like ITX/microATX/mid-tower/full-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?

Good looking case would be nice.

Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?

Nope.

Extra info or particulars:

So here's where the challenging part and I'd REALLY appreciate it. Because of shipping to Puerto Rico I would strongly prefer to order stuff from Amazon and/or Newegg, also the PSU most be from Newegg because Amazon won't ship any here (for some reason :( ) Thanks a lot!!!!
