In the quiet aftermarket of enterprise computing, a UK seller has placed a relic of corporate infrastructure — a fully populated HP C7000 blade enclosure — on eBay for £500, a price that sits in striking tension with its estimated $4,000 resale value. The bundle, carrying sixteen server blades, 128 physical cores, and a terabyte of DDR3 memory, represents the strange economics of legacy hardware: old enough to be abandoned by vendors, yet valuable enough to sustain a secondary market. It is a reminder that in technology, obsolescence and utility are rarely the same thing.
