The internal cable routing is not a bother to change.
Wait until you lay that cheap japanese steel frame into a quick downhill chicane, boy are you going to smile.
The internal cable routing DID suck. Our in house ghetto rigger sharpened a spoke to a fine point and that helped to "channel" the end of the housing through the frame.
Right now after owning it for less than a week its become a 9spd w/ Dura Ace cassette, 600 Ultegra rear deralleur, Ultegra front derailleur, Tiagra STI shifters, LOOK carbon fork, swapped out the 7spd freehub for an 8/9spd (obviously)... rides like a dream and is pretty darn fast considering the heavy heavy Araya/shimano wheelset and some other older heavy components that still remain. Next up is the wheelset, cranks and seatpost. After that I'm predicting it will be about 19lbs (currently 21-ish). The ride is unbelievably comfortable.
