I think I'll replace the Enermax listed in the left side of my sig (it's out for RMA, and I need one fairly soon for a LAN). I need dual PCI-e, 2 SATA/2 Molex. That's about it. Powering that system (uses the older 10 watt DDC pump), with 3 120mm fans. How much power? I want it quiet and reliable, and modular is a big help. A good 400 would probably do well, but I always go overkill. Can't help it.
