For in-store pickup only, Micro Center offer the Apple iMac Intel Core i5 2.9GHz 21.5" Desktop, model no. ME087LL/A, for $999.99. That's tied with last month's mention as the best deal we've seen for this model. (It's a current low for a new one by $189. In fact, Apple charges $189 more for a refurb — this one's new.)
Features include an Intel Haswell Core i5-4570S 2.9GHz quad-core processor, 21.5" 1920x1080 LED-backlit LCD, 8GB RAM, 1TB hard drive, Nvidia GeForce GT 750M 1GB graphics, AirPort Extreme (802.11n), Thunderbolt, FaceTime HD camera, Bluetooth 4.0, Gigabit Ethernet, Apple Wireless Keyboard, Apple Magic Mouse, and OS X 10.10 Yosemite.
