Sorry...I got the model number wrong. Go with the modular. It costs more, but it's worth it. The only beef I've had with the 900 is it's lack of cable management features.
If I get my computer sold for more than $1,000, then I can get the stuff I want. Right now I'll plan on getting the modular, but if I have to lower the price of my computer that much, then I'll go to the cheaper one.
