Get rid of the Asrock(ash rot) board for sure. You could look over some Asus, MSI, Gigabyte, or even DFI or Abit models to see a better build. Prices on cases vary greatly. You can get "CHEAP" cases and even get a "CHEAP" power supply included along with it. Some half way decent mid-tower cases run at about $45-50US and climb from there. You will want a good name 450w or higher supply to run the system if you plan on having more then one hard drive(like SATA arrays) along with additional optical drives like a dvd burner along with a cd rom drive. If you are planning a gaming build a case with good air circulation like seeing front vents at least will keep temps down as well as 120mm not 80mm fans. Having had to completely rebuild a system including case lately the two led 80mm fans are now on the clear side panel. Unfortunely the 140mm intake fan on the front doesn't work after completing the build(cheap fan apparently) on the Aerocool case.
