Cheap is good. I ran a 1.4Ghz Tbird based system, with a GF2 Pro, two IDE HDDs, a CDRW drive etc. (very decent system) on a 425W L&C without problems. As a matter of fact, I've encountered more performance issues using Antec PSUs than the L&Cs.
Of course, I run a 431W Enermax PSU in my main workstation.
