It features three M.2 slots, with the primary slot supporting PCIe 5.0 for next-generation NVMe drives, while the remaining two slots operate at PCIe 4.0. Four SATA III connectors provide additional storage flexibility. For expansion, a single PCIe 5.0 x16 slot is available for a dedicated graphics card. USB connectivity is extensive, including USB 3.2 Gen 2 Type-A and Type-C ports, multiple USB 3.2 Gen 1 ports, and eight USB 2.0 ports in total.
