I have the chance to buy a box of xeons like the ones in this link Compaq PIII Xeon X700 Pentium III Xeon, 700 MHz (175292-001) Processor Upgrade - Processors - Product Reviews and Prices - Shopping.com

They come with heat sinks but i wondered if anyone knew if these were copper and aluminum or just aluminum heat sinks? It will cost me $45 for 40 of these. Is it worth it?
