Looking to build my first computer

[xryanx123]

First I'm not 100% sure on the compatibility of the items I have chosen.

Case- Rosewill THOR V2 Gaming ATX Full Tower Computer Case, support up to E-ATX / XL-ATX, come with Four Fans - 1 x Front Red LED 230mm Fan, 1 x Top 230mm Fan, 1 x Side 230mm Fan, 1 x Rear 140mm Fan

I am looking for a long lasting, quality gaming system that can play most any game at a decent setting, as well as hold it's own for awhile before needing serious upgrading.

My serious problem right now is $$, if you can spot any easy ways to trim money off this build for comparable results I am more than open to suggestions.
Thanks for your time and help on the matter as I would consider myself an amateur in the building-your-own-pc matter.

You can't put an Intel processor in an AMD motherboard.

You need a power supply.

Avoid G.skill ram.

You need a video card if you are going to game.
