Adding new USB3 ports to my Linux Desktop computer (1 reply)

I have been wanting to add external USB3 ports to my old AMD64 PhenomII X3 Linux desktop computer running on an old debian v7.1 OS. So, after lurking around AliExpress, I gathered all the products and listed them below. Originally, I just wanted to add some external USB3 ports. So, item #1d listed below seemed to be a perfect solution. However, the more I digged, the more I found. For instance, item#2 looks pretty interesting because it also provides 1 eSATA port and it doesn't look like it uses any VIA chipset. However, these ports are all located at the back of my computer and a bit harder to reach. So, comes in item #4d (5.25" Media Dashboard USB3.0 HUB All-in-one card reader with ESATA Slot LED), but at more than 2x price the item #2. However, I am a bit confused where to connect the blue connector that looks like 1/2 the size of a PATA connector. If this is an internal USB3 connector, then I guess I can't use it on my computer (Asus M3A76-CM mobo) that doesn't have any USB3 ports. Does anyone have any idea?
