    My computer vendor uses these:
    http://www.amtrade.com/pc/ata133_ide_mobil_hdd_racks.htm

    I personally have not used them, so don't blame me if they end up not
    working as advertised, but my vendor is happy with them. I have also never
    used that company or its website until today, so I have nothing in the way
    of recommending for or against.

    It came to my attention that FreeBSD 4.x lacks USB 2.0 support. I used these
    USB 2.0 trays in a Windows server and hadn't thought that USB 2.0 might not
    be supported in FreeBSD 4.x. I don't use USB in my FreeBSD servers, so this
    never crossed my mind.

    I'm providing the link to the HDD trays above to show my apologies. :)

    Cheers,
    Brent
