for example

550 watts maximum output
2x80mm dual Red LED fan design
3 position switch for adjusting fan speed
Shielding tube on mainboard connector for reducing EMI
Built-in voltage overload protection
2 Serial ATA connectors (for serial hard drive)
Voltage switch for 115/230V AC input
AC inlet, monitor outlet, and On/Off switch
Support Intel "Pentium-4" and AMD "Athlon XP"
Complies with ATX 2.03 and ATX12V 1.1
Certified by UL, CB, CE, TUV, & FCC

the blue one for example is marked down from $39 to $21..also AFAIK free shipping......so if they are any good it would be a good deal?

Of course if they suck, it's no deal at all!


Any ideas or experience with these?

Thanks, JP
