At some point you'll need to be able to access the inside of the computer to install the hard drive. You could do a clone using USB & adapters but a: it would be very slow and b: you'll still need to eventually install the drive to an internal sata port as I said.

Also TrueImage 2010 is not capable of dealing with SSD's. You'd need to upgrade to 2012 or later or use the cloning software that comes with pretty much all new hard drives (and is usually a recent version of TrueImage cloning software).
