My dealer's USB2 case:

79.30 €

Other dealers are still around 25.00 € for a 3.5" SATA/USB 2 case, so it would be around
75.00 € still for 1TB
The WD I bought:
http://www.reichelt.de/External-HDD-3-5-8-9cm-/WDBAAU0020HBK/3/index.html?;ACTION=3;LA=2;ARTICLE=101545;GROUPID=722;artnr=WDBAAU0020HBK
95.90 € for 2 TB (but around 1 TiB, maybe 1TB would be ok), but
this was the absolute price limit for me. In the next three
years I might do schooling to became a registered child
care worker (I'm a 46 years old audio engineer but can't
stand this business ;), so I won't have enough money in the
close future.
If spinning down all the times or using a script to prevent against
spinning down should shorten the lifetime, than indeed it would be
smarter to buy a case, since I don't know if I can open the WD case and
replace the drive. I even don't know it it's SATA inside. 14 days sale
or return, it was delivered at 2013-02-28, so I still could give it
back. I will not give it back, but test it, but I wouldn't order it
again.

and it's just a little bit warm. Heat isn't an issue, but perhaps
continuous operation, the count of turns, I'm not sure if those drives
have the same motors as internal drives.
