You dont mention the kind of work you are using this for .
Some looks to be expensive overkill though . You are paying way too much for a power supply for instance , and its not going to be particularly quiet either
Sorry, i'm going to be doing intense video editing, 3d rendering and artwork. Adobe After Effects, Photoshop, Maya, Cinema 4d, that sort of stuff.
Is there a better power supply that would be quieter and still modular? Please let me know!
