That looks like it will do the job for you. It is externally powered and has a USB 2.0 interface. You should be able to install the hard drive from your old computer in the enclosure, connect the USB cable and power adapter. Boot your new computer, then plug in the other end of the USB cable to a port on the new computer, then turn the power switch for the external enclosure on. Your computer will likely indicate new hardware recognized and a new icon will appear in the system tray (systray) in the lower right side of your display. That indicates the presence of a USB mass storage device. Then you will be able to open Windows explorer, expand the content of the drive and simply drag and drop whatever files you wish to move to your new computers hard drive. Be sure to read the instructions which will probably come with the unit in case there is anything that varies from the process I've described.
When you want to shut off the external drive without turning off your computer, move the mouse cursor over the icon in the systray and a small box will appear saying "safely remove USB Mass storage device" followed by a drive letter. Left click inside that box and after a few seconds, the icon should disappear. If it does not, move the mouse back over the icon and that should make it go away. Now you can turn off the power switch on the enclosure.
If you are going to shut down everything, do a normal shutdown of your computer and when it is off, turn off the external drive power switch.
The reason for these procedures is to make sure whatever has been changed during the time the device was connected is saved.
Regarding those acronyms... IDE is an old term used when PC's were first coming out to identify the internal hard drive. It means
Integrated
Drive
Electronics. As time went by and variations developed, the term ATA came into vogue to designate what had previously been referred to as IDE. Further development of hard drive technology came up with SATA (Serial ATA), so the term ATA was changed to PATA (Parallel ATA) to differentiate between parallel and serial ATA drives. The primary difference in the physical configuration of the two is the electrical interface. PATA uses flat ribbon cables and SATA uses round shielded cables.
SATA is the technology currently at the top of the heap. Your new computer has a SATA hard drive. Its all a bit confusing and not really necessary to fully understand. Just be content with the knowledge your old drive is a PATA and the drive in your new computer is a SATA. This in no way inhibits the two drives from working together as long as the interface provides compatibility. The USB buss provides that interface.

BTW...the foregoing is another way of inserting a link into a post here on TSG. As far as I know, this is the only forum with that kind of option.
Good luck with your endeavor and enjoy your new computer. Let me know how everything works out... Raybro
