Glad that my HK$160 old 2.5 inch harddisk case works great with 80Gb HD

I was pleasantly suprise that the HK$160 2.5 inch harddisk case (it's so generic that it doesn't have any model number) works great with my newly brought Samsung 80Gb 5400rpm harddisk. I particularly like the fact that the Dell Optiplex GX280 computer in office can be drive the harddisk WITHOUT an additional power cable. I cannot say the same thing with my Look A6 OTG harddisk. But then, they have different usage.
