    Can you recommend a Mini PC chassis for this PCI Express card ?
    Thanks in advance

  • Howdy,

    I can’t, sorry. Also the AEX410 has been usurped by the A4B card. The A4B is low-profile, in addition to being half-length, so it should be even easier to find a smaller chassis that can accommodate it.
