Install an SSD in your Dell Optiplex 745, 755, 760, 780 minitower

I’ve been blown away by the performance improvements that SSDs make, even in older computers. The desktops that I sold for years was the minitower version of the Dell Optiplex 745, 755, 760 and 780. Since the hard drive bracket in those models is made for a 3.5 inch hard drive, SSDs don’t fit. I tried a few of the popular 3.5 to 2.5 inch adapters, but they didn’t work (as shown in this good blog post).

I finally found an adapter that does the job, not perfectly, but it’s not bad. It is a Mushkin 2.5″ to 3.5″ SSD adapter (Amazon link).

Install it in the adapter this like this and it pops into the Dell hard drive caddy (it only fits with two of the four holes, but it is relatively secure), then stick it in the case and you are ready to fly!

    The 745 (desktop) dualcore does not have AHCI support, tried 2 SSD drives no luck. Internet says this model is therefore not compatible. Just so you know. I think the small and ultrasmall do work though.
