Why dont you get a cheaper case and use the money you save to get some better components, Also as your on such a limited budget you may want to look at some AMD processors such as the A series
that is basically the cheapest case i could find. also this is one of my first builds (2nd actually) and last time i got a cheapo case and i took hours to install everything cuz i didn't come with some screws, and the metal was cheap quality. i dont want that to happen again.
with my CPU, is there a huge difference in performance between the one i have and the AMD A series? if there is can you recommend an AMD because i am not very familiar with AMD processors.
