Well, this thread title caught my eye.

I have a PC-65B...thought I haven't yet played around with it..long story.
A slight addtion to what Dr. mechBgon said. True, the 65B does only come w/one REAR exhaust fan. But it also comes with one TOP exhaust fan. While this is not as good IMO as a second rear fan, it is still an exhaust fan nonetheless. Heat does rise, afterall. It should grab the heat from the optical drives and any heat that manages to sneak past the rear exhaust and PSU fans. It should work well, IMO. Proof is in the pudding though, so we'll see what happens. LianLi makes high-quality stuff; I doubt they have a fan-scenario that didn't work well. But again, we'll see.
I may cut that second hole out myself, depending on what I find my case temps to be. That will take some time to sort out. Oh, I dunno..I will be cutting stuff left and right anyway. I plan on duplicating most if not ALL of the great ideas that mechBgon came up with for his case. They look great and work well.
AFA the drives go, yeah, that's the one major drawback to a black case; you've got to get all black drives or black faceplates, else it's gonna look like @ss.
I decided to go "all the way" w/this build; I bought a black DVD-rom, black CDRW and a black floppy. Sure, i could've dyed the faceplates (PITA) or bought the stick on faceplates (didn't think of that one) but I needed a new DVD-rom anyway...and I figured "what the heck, why not?"
I'm planning a black w/blue lighting theme. Solid black front, save for some "special" LEDs, a white text on blue background LCD (yes, LCD as in a Matrix Orbital screen

) and blue CCFLs inside. Blue rounded cables and black sleeved PSU cables...to better hide them. I plan on stealthing them where possible, like mech did.
Good luck w/your case. Post pics!!
