I went to CompUSA the first time and I was surprised at how much computer stuff can fit in one store. I was looking for an external hard drive case and no one carried any. I went there and they had three different models to choose from. I was amazed at how knowledgeable the staffs were. The prices for most of the items were a little on the expensive side but they did carry name brand computer parts and not just parts relabeled as being from another manufacturer.
