When I built my dev machine at work, I used a cheapo 750watt PSU that we stock for replacements on customer machines.  I burned out 3 or 4 of those before deciding that the swap time and associated hassle justified buying a good one.  I've had excellent luck with both thermaltake and antec PSU's and the new 80plus certified PSU's run really cool and quite (a nice side effect).

Thanks!  I'll keep that in mind.  In any case, it's apparently no
surprise I had an issue with the original PSU.  From what I've read,
the original PSUs that Dell used on the 4600s made around the time
that was purchased (between 2003 and 2004) apparently failed very
frequently.
