Hello,

You can either remove the optifcal drive and add another hdd (use a usb optical drive for when you need one) or install a 2 port sata card thats has drivers for the OS. such as this one. I just picked a random card with some server drivers and half-height since you may need that depending on which optiplex you have... not that I'm recommending yourun out nd buy this. do you homeowrk and find one that works with your system and budget. http://www.newegg.com/Product/Product.aspx?Item=N82E16815158097
