i'd like to know if all this stuff is compatible and if it would all fit in the case i've picked. I believe it will but im not tech savvy enough to know. id hate to know something wont work out once i have the parts in hand.

Also, what monitor would you guys recommend? something under $200 that my build can take full advantage of. id rather have a monitor that my pc runs at 95% then have a monitor that my pc runs at 50%, feel me?

lastly, does anyone know how i can get os cheaper than buying it full price? i kinda wish i had the 90 bucks to spend somewhere else.

feel free to leave me your thoughts/opinions on the build, and how hard it would be to put together.

thanks guys

Yes it is certainly compatible and the case will provide plenty of space. This will be a very solid build.

No, you need to buy the OS. Unless you are a college student and can get a discount through school, looks like its $90 at the cheapest.
