In an effort to bring space-saving and budget-friendly computers to the home user market, Lenovo launched its line of Desktop Essential computers. The Essential desktop line is mostly comprised of all-in-one computers. They are ideal for multimedia use and day-to-day home use. Essentials can claim the benefits of powerful CPUs like the AMD Athlon II X2 250U processor and the Intel Core i3-540 processor. As for the memory system, these models have at least 4GB of maximum memory, though some PCs have 8GB. The expansion slots available vary from four slots to two slots, depending on the total memory capacity.
