Florence

I thought I could just buy a case and plug it into my computer by a USB port, boy was I wrong, I am one that knows how to do things on the computer but when it comes to putting things in like a hard drive I am lost.
I have a almost new burner I would like to install too since this computer only came with one. I guess I will wait for my grandson to come fisit, he builds his own computers.

Thanks for trying to help me.
