Wider system bandwidths & lower latencies

Built-to-order 3U, 4U, or 5U chassis with up to 18 PCIe slots at the target system allows a flexible, general purpose system solution for high-end blockchain technology, data gathering, data storage, video processing and graphics in government and defense, industrial automation, and test & measurement applications.

The PEU8039 x16 PCIe host card and the PED8044 PICMG 1.3 target card allows you to expand your computer effectively adding more PCIe slots. 

The 4U and 5U options allow room above your GPU cards for the 8-pin aux power to be plugged in.

Customize this rugged expansion chassis with our wide array of standard internal components.
