No! Stay away from that cheap internet junk. God only knows where it is made and it likely won't interchange with other brands when somebody else goes to replace the jack or add another to the plate. That's big enough of a problem with the name brand stuff.
As for using CAT5e jacks for voice again a big no. You have to pay attention to the wiring because they are not USOC. Repeated insertions of a 6 position plug into an 8 position jack can damage pins 1 and 8 of the jack.
As for possible future use for a computer, who cares. Besides you are using CAT3 cable for voice, right?
Data jacks should be a different color than the plate (we standardized on orange) voice is usually the same color as the plate. Besides that they cost more (well, maybe not for the junk).
