Iam having some problems find out what the difference is with these 3 cases.

1 . PC-V2000B http://www.lian-li.com/Product/Chass...S_PC-V2000.htm

2. PC-V2000Bplus http://www.lian-li.com/Product/Chass...-V2000plus.htm

3. PC-V2000BplusII http://www.lian-li.com/Product/Chass...2000plus_2.htm

It look like nr 2 has a fan at the Grafikcard and nr 3 also has one.

But I must admit it is very hard to find anything different about them
Thanks in advance for your assistance.
