Looking at specs you have
"(1) USB 2.0 compliant / e-SATA port with PowerShare" You would want to use the esata. This brings up power, will need a brick (external power), or an adaptor Power-from-a-usb port.
Your Intel G2 only requires 160mW active (typical), a Usb port can supply a MAX of 2.5 W. Note: many people indicate enclosure does not work - the reason is they are trying to power it from the usb port and a mechanical HDD may require up to 5 W which excceeds the USB 2.5 Watt max limit.
I bought this one. Like becaues it fits pocket and worked.
Note One reviewer knocked it down because he had to use two cables (esata and USB - for Power) - Dah - esata does not care power, and must get power from some where.http://www.newegg.com/Product/ProductReview.aspx?Item=17-159-093&SortField=0&SummaryType=0&Pagesize=10&SelectedRating=3&PurchaseMark=&VideoOnlyMark=False&VendorMark=&Keywords=
Here are two others that meet your needs
(1) Plus - Comes with a USB power cable, no power adaptor (Just pick up a 5V adaptor made for plucking int a usb extender. neg - seems to have a high 1/2 egg rating, But some of the poor ratings are individuals using a HDD that requires more power than can be provided from a USB port!!! http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16817193058
(2) Plus comes with a power adaptor, neg high priced, no USB power cablehttp://www.newegg.com/Product/Product.aspx?Item=N82E16817145079
