Selling a Dell desktop motherboard pulled from a compact PC (similar to OptiPlex 3040 / Inspiron 3250). This board uses the Intel LGA1151 socket and requires low‑voltage DDR3L memory. According to Dell’s small‑form‑factor documentation, systems in this range support dual‑channel DDR3L memory in two DIMM slots  and provide one PCI Express ×16 slot and one PCI Express ×1 slot  for expansion.
Key features
• CPU socket: Intel LGA1151 (6th‑gen Skylake / Pentium / Celeron processors)
• Memory: 2× DDR3L DIMM slots (up to 16 GB total) 
• Expansion: 1× PCIe ×16 slot and 1× PCIe ×1 slot 
• Storage: Several SATA connectors for HDD/SSD (SATA III interface).
• Rear I/O: Combination of USB 3.0 and USB 2.0 ports, RJ‑45 LAN, audio jack(s), and video outputs such as HDMI and DisplayPort (exact ports may vary by model; OptiPlex 3040 SFF specs list one HDMI and one DisplayPort ).
• Power: Uses Dell’s proprietary power connectors and an external DC‑input (no standard ATX power supply).
• Form factor: Compact desktop board suitable for small form factor (SFF) or ultra‑small builds.
Condition
• Used / untested. The board was removed from a working system but has not been bench‑tested; therefore it is sold as‑is with no returns or warranty.
• Physical state: Appears clean, no broken components. Includes only the bare motherboard—no CPU, RAM, or cables.
Compatibility
Ideal replacement for Dell small‑form‑factor systems that use an LGA1151 socket and DDR3L memory (e.g., OptiPlex 3040, Inspiron 3250, Vostro 3250). Please verify compatibility with your chassis and power supply before purchasing.
