Price is high due to the fact it has Fan. Im having Cooler Master X craft 350 3.5 Sata with Esata + usb. Now it was two times that power adapter has stopped working and the power adapter looks very strange and different , Not available anywhere separately. Like this in image :-http://bixnet.net/images/Connector-PA215-4Pin.jpg rather than standard ones.
Now i have ti buy new enclosure.
I will buy this transcend one.
