In just a couple of days, Apple will be putting the venerable Xserve line of rack server Macs out to pasture in favor of the Mac mini. So if you need any, get hopping… just don’t expect Apple to do the same in shipping them out. In fact, the Apple Store is now listing both the Quad-Core and 8-Core Xserves as not shipping for another three months.
January 31st may mark the end of the Xserve line, but don’t fret if you need servicing: Apple will still be selling 160GB, 1TB and 2TB drive modules until the end of the year, as well as servicing any units that go awry.
Anyway, if you need an Xserve, better start moving: after January 31st, you’ll have to choose between a Mac mini or a Mac Pro with Snow Leopard Server installed for your intranet needs. Good luck cramming those into your existing racks.
