Hello, i'm new to all this hard ware stuff and i've just found out i need to buy a new case because the mother board does not fit into my old DELL case . i'm only 15 and i want to know for sure before i buy the Antec VSK-4000E ATX Mid Tower Case that my ASUS M5A78L-M LX PLUS mother board will fit into it.
You can purchase most any case, micro, mid tower or full tower for that board. Dell has their own boards for their various computer models that make it hard to use again sometimes, especially with other boards and etc.
And yes, that case will work for your board that you have picked out.
