I am building a new system and would like to get the charcoal black Antec SX1030B case. It only comes with the 300W Antec PSU, however, and there is no SX1040B. I was wondering if you think this would be enough power for a 1gig T-Bird @ 1.33gig, a 40gig IBM HD, DVD-ROM drive, 12x10x32 CDRW, Sound Card, 512mb PC2100, and all the other common stuff. Or do I need to get a different PSU for it? Also, will the Palomino require more or less power? Thanks in advance.
