Processor: An Intel Core i3 2nd-generation CPU, such as the Core i3-2120. This processor was released in the early 2010s and is capable of handling standard productivity software, web browsing, and multimedia playback. Memory: It includes 4GB of DDR3 RAM, which is sufficient for light multitasking but may be a bottleneck for more demanding applications. This can typically be upgraded to 16GB or even 32GB, depending on the configuration and form factor. Storage: A 500GB Hard Disk Drive (HDD), which provides ample space for documents, photos, and general files. Some refurbished models may be upgraded with a Solid State Drive (SSD) for faster performance. Graphics: The desktop uses integrated Intel HD Graphics 2000, which is adequate for basic visual tasks, but is not suitable for gaming or high-end graphics work. Connectivity and ports: Typical configurations include multiple USB 2.0 ports (some may have USB 3.0 via an add-on card), DisplayPort, VGA for multiple monitor setups, and Ethernet. Operating system: Refurbished units commonly come with Windows 10 Pro, though some sellers may offer older or different versions.
