Thanks for the confirmation.
I've already got the venting system in place and it's worked perfectly for years now...other than sometimes the fans run too long since the thermostats are set too low. I'd have to reverse the air direction for the new projector, but that's not hard.
The fans are in adjacent rooms. I can only hear one fan in my upstair office, but in the theater itself, you can't hear them at all. It's a nice conservative heat protection...total overkill I know, but I do that a lot - and I'm OK with it.
My room doubles as a recreation room for my kids and general family. It keeps the mess to a tolerable level when unexpected guests arrive for the rest of the home.
Still, as a two channel/HT room, it is quite durable and practical. I've even gone to the extreme of having it acoustically certified, but it doesn't look abnormal.
I've taken a year sabbatical from A/V, and am interested in updating and enjoying again. Even looking at doing a Seymour Acoustic curved screen and putting my center up at ear level. It's a small theater for most of those looking here (I'll be about 9' from the screen), but I like fabricating my own bits and having it look truly right.
Ideally, I could have a third Legacy Whisper as my center channel. That would make some 3-ch SACD listening really interesting. (please - no SACD is Dead comments...I know that already)
Thanks again Milt99...
