listing is for a lot of two (2) Dell Precision Tower 3420 Desktop SFF computers, selected at random from a larger mixed lot of 14 total units available. Each unit includes only the chassis, motherboard, power supply , and CPU cooler/heatsink; CPU, RAM, storage (HDD/SSD), and operating system are not included, and buyers must install their own components for the systems to function. Photos are representative of the model only—the systems come from a mixed lot (see photos of the full lot), and the exact units received may differ cosmetically but will be the same model and configuration as described. These units are being sold for parts or repair, with no guarantees, warranties, or returns, and condition may vary between units, making this lot ideal for parts harvesting, repair, or refurbishment.
