A $18 power supply?  450 watts?

I'd hesitate.  Big time.

Consider a brand like Sparkle (FSP series), Enermax, Antec, or PC Power and 
Cooling (when someone else's paying-- nice supplies, but expensive)  
Realistically, a 350 watt supply works fine for most users, when it's a good 350.  And 
you don't plan a Geforce 6800 drawing off it.

Elitegroup motherboards... sometimes.  A few models (notably Athlon boards 
with the SiS chipsets) developed a strong user community.  Others, good luck.  
Other models go barely supported.  Also few tweaker features.

I saw the Artec burner at 79 after rebate in Fry's ad.
