This is a fairly new (lightly used) unit from a project which was canceled. It has an internal and an external port. I will throw in a cable for each - internal fans out to 4 sata/sas connectors, external has an sff-8088 (mini-sas) connector at the other end. Standard height bracket (I believe it also includes a low-profile bracket.) Asking $300, with free shipping to US/48. Paypal only, please.
