Hi there
On some of those older computers it's no point getting a USB3 card as the bus speed might not be capable of handling the USB speed throughput.
Also the older HDD's are probably IDE (those connected with the thick 20 pin ribbon cable) which are as slow as molasses anyway -- HDD's should be SATA connected these days.
It seems to me you might be better off looking for a new machine -- often there's quite OK used / refurb'd ones on amazon if you don't want to spend money on a new one.
Cheers
