eMachines is just here to help. The low-cost PC maker has introduced a few new desktop models, destined to sit beside your paper plates, can of beans, and tin of generic instant coffee. Not that there's anything wrong with that, mind you. The new budget models come in two flavors, the T3646 and T5254, both featuring AMD CPUs (2.2GHz Sempron LE-1250 versus the 2.1GHz dual core Athlon BE-2350), an NVIDIA 6100 graphics chipset, 1GB or 2GB of RAM, a 160GB or 320GB hard drive, DVD+R/RW SuperMulti drive, a handful of ports, a mouse, and really nasty looking cases. Available right now, $299.99 and $399.99, respectively.
