The LaCie Porsche may look good, but they don't have fans inside for cooling. Anyway, since you're looking for enclosures, have a look at dealsonic.com - I've bought enclosures from them in the past and am happy with the products. They have a good variety of enclosures - so you may find something you like.
Going slightly off topic, if this is for making a new external hard drive, then I'd suggest going for a branded external drive. The days of buying an OEM HDD and putting it in an enclosure to reduce the total cost are almost gone. The best deals for branded external drives now are better than a DIY (enclosures usually cost upwards of US$30 and that cost hasn't come down much in the last two years or so, unlike the price of branded external drives).
