Meh, that's like buying a pc off the shelf then upgrading a few things here there. I've not done that since college. Always bought my own individual parts and pieced my system together starting with an AMD K6/2 266 mhz on an AT motherboard. Just don't really care to do that.
That's the spirit!!
Out of all the AR variations I've had, only one was complete when I acquired it; and it was my least favorite.
