Two reasons, I guess - first, an external hub is yet another bit of kit 
cluttering up the place. An internal device is somwhat tidier, IMHO.

Secondly and perhaps more importantly, this hub card draws and supplies 
power direct from the PCI bus, so it can power devices with up to 500mA 
per port with current limiting, without putting a drain on the power the 
main USB host provides. As it turns out, I have four spare PCI slots 
(three now), so the loss of a slot is no hardship.
