For its newsletter subscribers only, newegg offers the OEM Microsoft Windows Home Server 2011 64-Bit, model no. CCQ-00128, bundled with a $10 newegg gift card for $49.99. Coupon code "EMCNENB246" cuts it to $39.99. With free shipping, and assuming you use the gift card, that's the lowest total price we could find by $20. (We saw it for $8 less, without the gift card, less last week, since expired.)
