Dell R640 4x3.5" 3PCIe

This Dell PowerEdge R640 barebones server is a 1U, 14th-generation configuration base with four 3.5-inch front drive bays for SAS or SATA storage and a three-PCIe-slot expansion layout. The large-form-factor bay layout should be paired with the proper 3.5-inch drive carriers, backplane cabling, and PERC or storage controller, while the PCIe configuration depends on the installed R640 risers and supported low-profile expansion cards. Final configuration depends on the selected processors, memory, heatsinks, power supplies, fans, storage hardware, and other Dell R640-specific components required for the intended 4x3.5-inch and 3-PCIe chassis layout.
