I see there is a great deal on the Chieftec w/ 420 watt power supply. I was really leaning towards the Antec SX1040B but this one is about $30 cheaper. Is there any reason why I should NOT get the chieftec? I already have 3 Panaflos so not coming w/ fans does not matter. I will be putting an Asus mobo and a P4 1.6A. Help me out please people. Thanks.
