Hey Bobbie,
Good to see all the help you're getting.
One thing i noticed, which i dont think anyone has picked up on yet, was that your current computer is an Acer. If its like most of the generic pc's you buy from big stores, the case will likely not be able to fit the GPU you have chosen or the full size ATX motherboard.
Check if your motherboard has 4 expansion slots, if it does, you will need to buy a new case to accomodate the new board.
Regards,
Matt
