Basically this will be my first PC as i have been using an old laptop for a long while. That is why i cant play a lot of games currently. I wanted to invest more in this and make a gaming rig that will last me for many years to come. Would prefer some really cool looking casing as well. Thanks for help in advance.

Thanks Man !
