not sure how you refurb something that does not have any moving parts. Maybe straighten out the pins? In any case, all the servers I upgraded had a matched par of cpus. I guess you can chance it if you have a burnt cpu that needs replacing. At this price, get a few.

Xeon cufflinks. Yeah baby. {licks thumb, brushes eyebrow}

You can buy 100 and create a puzzle
