EMC2 KTN STL3 EMPTY RACKS | eBay starting bid $10, ends in 6 days. The lot is listed as "For parts or not working". My understanding is that it just means "no returns" but the enclosures are functional. The pictures are low quality but it looks like power supplies, midplanes and line cards are included. I would estimate the resale value at $50 per unit. Conservatively, $40 + shipping.
