It features 4GB of memory; a broader choice of processors including AMD Athlon II, AMD Phenom II, Intel Core i3, or Intel Pentium E6600; and a much larger 1GB hard drive. Its basic version offers just integrated Intel graphics (unlike its peer, which comes right off the bat with third-party graphics), but can later be upgraded with an Nvidia GeForce 9200. Signature to the M3 Series is its improved connectivity options, which include HDMI, a single PCI Express slot, an open PCI Express x16 slot, and over 11 USB 2.0 ports.
