Ignore the side fan read my last post! Does not have side fan mount.
Your board appears to be all 4 pin fan headers, I use a fan controller so I have no use for it. It's a nice feature though.
I would get 2x120 and 1x140 for top. If you can afford it get more! XD
Sorry, you are quite right (I am wrong - not for the first time).
Can see 7 fan fitting positions:
2 top, 2 base, 2 front, 1 rear. Thanks

I'm getting interested in them now too hehe.
