The answer is '''no'''. Please see step 7 [guide|6131|here]. There is only 15mm of "extra space" underneath the factory original 9.5mm drive. Actually for a number of reasons should not attempt to put 1 in there with a standard 9.5mm drive. Read the reviews [http://www.newegg.com/Product/Product.aspx?Item=N82E16822148710|here] on the Seagate Constellation.2 ST91000640NS hard drive. It is a power hog the Mini's power supply more than likely couldn't power it up and if it did you would suffer other consequences in the USB realm and others. It runs very hot, not a good thing in the mini. If you got to have internal Terra drives go with the newer WD Scorpio Blue Or the Samsung for inside the Mini.

Personally with a Mini. I would go with a SSD for my operating system, virtual memory and programs.Then a larger slower hard drive for data. It is actually the hard drive that the virtual memory is placed on that makes the biggest difference in a computers performance. After that, it is the hard drive the operating system is on that determines how snappy a computer performs. Your data hard drive doesn't need to be fast. It needs to be reliable.
