Actually, what he's suggesting is turning the HD's around so the wire connections are facing the front or motherboard side of the case. Usually looks much cleaner, but can get messy when you've got a fan right there (if the wires are facing toward the front). If you do it right it's pretty effective.
As far as the PSU sleeving, if you want to spend some time you can sleeve them yourself. Get a molex pin remover and go at it.
This is the most in-depth guide I've seen:

Obviously opening your power supply voids your warranty, but gives you a much better look (so the sleeving actually starts inside the PSU case).
Just do a search for "sleeving power supply" and you can find a lot of different how-to articles on it.
