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.
