$15 delivered if you shop around, particularly if you look for lots of two or
three. These power supplies cost upwards of $300 when they were in
active use, but the servers they were designed to work with have been retired,
leaving a lot of these server power supplies as surplus. Consequently,
you can get them pretty cheap. </SPAN></DIV>
