Well, if you want to permanently house the HDD, then an enclosure like that should work.
But, if all you want to do is get data off the HDD, then you can buy USB to IDE/SATA cables for about one tenth of the price; I use one for pulling video files off a Humax SATA HDD. You will need to provide power, though; my cable also came with a standard Molex 4-pin disk power socket to SATA power plug cable, which I connect to a spare disk power cable in the old desktop.
Windows should ASK you what you want to do with the unrecognised disk. Do not accept its offer to format it.
Yes, install the ext4 utility before connecting the disk.
