Do you have a link of it on their page somewhere ? It might be easier for me to tell you what I think if I can see what I'm talking about.

I bought it from Newegg a while ago. It's the PC-7B, which is essentially the PC-7 in black. Newegg has more pictures than Lian-Li's website on their product page, although those images don't show the blowhole fan that I definitely do have.

As for the fan sizes - I wasn't sure before but I have measured them now. They are all 80mm. And I do like the idea of having a fan controller. It's not often that I play games, so I could keep the noise down with one of those most of the time. On the page you linked, I think I like that 3.5" Nexus. I won't have more than 4 fans to control if I'm going to mod the case, and my 3.5" external bays are all unused at the moment.

So, in short, thanks for the advice. Think it's about time I call up my buddy and ask to borrow his dremel tool.
