SFF - Fits most mATX boards and any smaller sizes. Require ITX PSU and low-profile expansion cards. Knockouts for rear wi-fi antenna and three expansion slot knockouts. Front mic / headphone ports, two USB 2.0 / two USB 3.0 ports, I've built two 65W setups with GPUs in this model case before. They cool extremely well for the volume and can house a good budget home server or gaming setup.
These cost $70 each. Brand-new in-box, no SSD brackets. One or two 2.5" SSDs should fit with double-sided tape. Asking $50 each or $80 for both.
Troy area, can deliver with 50 miles of Troy for a small fee of $10-$15 for fuel. Cash only.
