Modular Power supply an cpu question.

[BrokenKingdom]

Ok so I'm forgoing just upgrading my video card and jumping right into building a new workstation and keeping the comp I have now for everyday use! Huzzah the more computers the better, I say! :)

This one will be strictly for 3d modeling and graphics design.

So as it is I have a

centurion 5 case.
Barracuda 320GB HD
ASUS M2n Sli deluxe (wireless) mobo *
2Gb Crucial Ballistix
Quadro fx1700 vid.

I'm trying to figure out what Power supply I want and I would love for it to be modular (I HATE messy cords) but I am having a hard time finding them. Any suggestions?

Also I'm not sure if I should run with a Phenom or an x2 6400.

*is the wireless feature any good or should I just stick with the M2n Sli Deluxe?

Thanks a ton guys much thanks! :)

For a modular PSU, can't beat the Corsair 520HX or it's big brother.
As for a built in wireless, I would look to see how it would be used: for surfing the web it would be OK but if it would be used for transfering file and such on a network, use the on-board ethernet.
Now for a workstation, I would be more inclined to go with an Intel Quad E6600 and a basic Asus or Intel motherboard used for workstations versus a gamer board.
