Hey, welcome to GTG.com. New here myself.
I haven't built a gaming rig in a while; so I am not up to date on the best performing graphics cards for gaming; however, take a look at these two cases as an option to the one you picked out. Everything else looks nice, and it looks like everything is compatible.COOLER MASTER Centurion 534 $39.99 + $9.99 shippingRosewill Smart One $39.99 + $9.99 shipping
I have used that Cooler Master case in some builds, and it has plenty of room with good air flow for keeping things cool. Haven't used the Rosewill case you are looking at, but the Rosewill one I linked to might be a better option. Several reviews from several sites complain about the sharp edges on the Wind Knight case and some cooling issues, but sharp edges can be fixed with just filing them down and of course cleaning the case before you began installing hardware.
According to Tom's latest GPU charts for 2010
, that Radeon HD5870 is fast.
edit: As far as your PSU is concerned, if you don't know how to figure out how much wattage your system will use yourself, MSI has a pretty decent Power Supply Calculator
you can use to make sure you are going to have enough juice at peak performance as well as if you decide you want to add another card later on to take advantage of the Crossfire feature or any other add-ons or peripherals you choose to run.
I also forgot to mention that you can go to MSI's site to also see if any of the components you have picked out have been tested for compatibility with that MSI 870A-G54 board: MSI 870A-G54 Test Reports
. If you don't find a listing for a component you picked out, it doesn't necessarialy mean it won't work; so don't panic, but it does help you in choosing hardware for your build.
I also forgot to give props to GTG.com's most excellent guide on How To Build Your Own Computer
