Intel Core 2 Duo processor and slightly different audio and video card options XPS 410 The former intermediate model of the XPS series and bigger brother to the Dimension E520. It features a base configuration of an Intel Core 2 Duo processor, and a 2.4 GHz Core 2 Quad is also available as an option. Other base options include the Nvidia GeForce 7300LE, 7200RPM SATA-300 hard drive, and dual-channel DDR2 RAM. The case is nearly identical to that of the Dimension E520, with an additional 3.5-inch drive bay being added. The case is physically taller because of this. The power supply is also slightly more powerful than the Dimension E520 (375 W vs 305 W, respectively and has an added 6 pin PCIe power cable). The XPS 410 replaced the XPS 400. It was replaced by the XPS 420. XPS 410 units were also sold as the Dimension 9200, allowing Dell to continue selling remaining units after the XPS 410 was discontinued. In an odd twist, the Dimension 9200 was the final desktop in the Dimension line, effectively making an XPS unit the last in the Dimension family. XPS 420 Now discontinued, it features similar components to the XPS 410, but it used different case design and new features. This was Dell's media based computer featuring the Dell Xcelerator (a simple and effective Video Recorder), and an LCD screen in the case, running Windows Vista SideShow. As usual with the 4XX Line of XPS's, it did not allow for SLI Graphics. The XPS 420 added support for 45 nm Core2 Duo/Quad/ and Extreme CPUs up to the QX9650. XPS 430 Similar to 420, with DDR3 RAM and without the LCD on the computer chassis. Studio XPS 435T (or Studio XPS 9000/9100), Studio XPS 435MT The Dell XPS 435T was a mid-tower desktop that originally shipped with a Nehalem-based Intel Core i7 processor. The system's motherboard used Intel's X58 chipset, allowing for 3 memory channels over 6 available DIMM slots. The XPS 435T is able to support Westmere-based Core i7 and Xeon processors (supporting up to 6 cores) with the latest BIOS update. The XPS435MT was a smaller Mini Tower version that shared the X58 chipset. Unlike the 435T, the 435MT's BIOS was never updated to support Westmere-based Core i7 or Xeon chips. The motherboard is a variation of the MSI 7591 MicroATX. XPS 600 series XPS 600 The former flagship
