I want to use the Corsair Carbide Series™ Air 240 High Airflow MicroATX case. The problem I don’t know what to buy to put in it. I want to game on it and use it for school work. My budget is $600- 700 if necessary. I prefer to buy on amazon or Best Buy. This is my monitor I use right now:AOC - 21.5" IPS LED FHD Monitor - Black & silver: 1920 x 1080 resolution with 16:9 aspect ratio. My theme is black and blue. I don’t want any other colors inside.
