I gather you havent
but it just comes down to wasting $120+ to get a 480 watt psu when you already own a 480 watt psu... just for for cable management? And this is coming from someone that OWNS a NeoPower 480.
I'd rather spend more and get an extremely high quality psu OR just keep the one you have and put a little effort into tying up cables nicer.
Of course.. I'm not saying the PCP&P psus are "cheap" but they are some quality stuff.
I say go woth the large LCD purchase, it will be something that will carry over to the next upgrade nicely, and you can enjoy it now.
Also that 480watt neopower actually creates a little MORE clutter with the motherboard connextor if you dont have a new motherboard that uses a 24 connector, you will have to use the 24-20 pin adapter and that kind of mucks things up.
