This deal has ended.
Dell has just kicked of a "10 Days of Deals" promotion, with a different deal each day through 6/21. Today, you can get an XPS 410 Desktop w/ 20" LCD for $899, the best deal I've seen by $100. The XPS 410 comes loaded with an Intel 1.8ghz Core 2 Duo processor, 2gb memory, a 320gb SATA hard drive, 16x DVD / CD burner, 20" UltraSharp widescreen LCD monitor, 256mb nVidia video card, Windows Vista Home Premium and 13-in-1 media card reader. Shipping is free. Of note: the 20" LCD and it's speaker attachment can be removed from the configuration, saving you $230 and cutting the system price to only $669.
