I have both an Enlight 7237 and an Antec SX830. I replaced the 250w in the Enlight with an antec 303X ps, same as the 830 and am quite pleased with both. However, the 830 is a big step up from the enlight, both in terms of quality and roominess. The enlight is only deeper than a mid tower while the 830 of course, is deeper and taller and the side panel is very handy. The box is quiet and cool, while the enlight is a little noisier because the fan has to rev up more to cool. This could easily be an ambient temp thing rather than a case issue. I use one in and one out fan in both systems and have similar setups. They're both nice but the 830 is more and you'll be happier if you can spend the extra money.
