Anyone ever had an Enlight 7200 desktop? Is PS good enough for Duron?

[bigshooter]

I want to buy 4 Enligh 7200 desktop cases to stack on top of each other for a test lab I am setting up. I just need to know if the 230w PS's that come with them are good enough for run a Duron 750 with no OCing. Other than that I'll just have 5400 rpm drive, maybe a cdrom, and an ATI 8meg vid card. I want to make sure this works before i go dump a grand on computer parts.
