Should a 3.5” external HDD enclosure have ventilation?

I should mention this HDD will be turned on for extended periods of time.

I'm concidering this 3.5” external HDD enclosure (case #2) link on bottom, however this portable case has no
Ventilation like my Western digital my book which is vented completely on top and on the backside.

the WD my book get's kindof warm so
?1. I'm thinking ventilation is mandatory?

Here's 2 links w/ image of the WD my taken apart so I assume when the HDD fails the case can be reused?
?2.I also assume I use fingernals on both side and just pull the case apart for disassemble?

If it should have a fan it would be designed with one.
I have that External HDD my self. I never think about it overheating.
 
OK you have the same Western Digital as I do

I don't think there is a builtin fan, next time you use it for a few hours put both you'r hands on the sides of it and feel how warm it is, mine get's kindof warm not hot just warm.

I like the price of the Hong Kong made HDD enclosesure maybe the aluimin type enclosures don't need ventilation maybe the aluimin absorbs the heat?
