To don't have projection room give's you save in space and less construction issue, therefor less money on start....probably?
But, to have booth get you far way better operation condition for equipment like easy maintence of projector, replacing parts and xenon lamps, space for audio rack, servers, way better ventilation of all components and less noise in room.
Without room you still need to find place for audio rack, data storage, etc....also booth can be used as storage for replace parts, lamps etc......

I can't support this idea at all.
Same here.
Too many issues arise without a booth:
Projector noise, serviceability, ventilation issues, subject to damage/vandalism/tampering, increased wiring costs, etc.
And where exactly will the servers be located?
If you were to look at the REAL, ACTUAL, total costs of the increased HVAC, Enclosure, electrical, mechanical requirements of a boothless setup for ANY number of screens I gaurandamntee you that it will cost MORE in the initial build AND ongoing operational costs than putting in a simple booth. (A LOT cheaper to build a single wall with a single port than to deal with all the other nonsense of boothless.)
Think about it, seriously.

Christie offers a "projector-in-a-box" solution, including a lift that lets you lower the projector for maintenance. I've never seen the thing with my own eyes, but they do have a promotional video.
But seriously, I also do think this whole concept is a bad, shortsighted idea after all.
Besides the fact that you still need space to accommodate stuff like amplifiers and (storage) servers, bring the whole wring to this box and provide sufficient sound proofing and ventilation to that same box, there are tons of other potential problems:
- What if there is a failure during the show that cannot be fixed remotely? In that case, you need to have technicians work inside the auditorium. You probably even need to evacuate part of it too.
Also, this whole DCI stuff seems to be rather short-lived compared to the good ol' film stuff, so keep in mind that you need to upgrade your equipment within the foreseeable future:
- What if you want to install a new projector? Does that fit in the same box?
- What if you want to install a second projector for stuff like brighter 3D? Or maybe a transition to a new system?
In your particular setup, you want to put the sound rack including the processor behind the screen:
- What if you want to upgrade your sound system? With your sound equipment behind the screen, you now potentially need to run new cabling from your projector to your sound rack.
- What if your CP750 craps out and needs a manual intervention? Or one of your amps has a problem? Do you have easy access behind the screen?
To me, this whole boothless thing sounds like a maintenance nightmare, especially if you go with that lift thing, which seems to be the only solution that makes some sense. Once that thing is in the box, there is no simple way of moving it and for every intervention, you need to lower it. Even simple things like fixing the RGB convergence (which cannot be done remotely with current projectors I know off) become a maintenance nightmare. Also, you now introduce yet another component that can fail: the lift itself...
And indeed, a booth isn't just wasted space, because you can use it to put your servers, your sound equipment, spare parts and even other stuff you want to keep safe, that hasn't anything to do with your booth operations.

We've now built a couple of 'boothless' cinemas, and converted the mini screens at another. It can work quite well, but you really have to take care to get it right. We count 'projector cupboards' as boothless, since access is strictly for service only.
We always include a 'control room', which as a minimum contains CP750s; alterntive content sources, switching and scaling; CCTV monitoring; tie line patchfields and associated mixers etc; TMS. For our first attempt, we also included servers and power amps. This didn't work terribly well and did cost a lot in cabling. So more recently we've moved servers and power amps into the projector enclosures. Personally, I'm not terribly happy with the idea of putting the amps behind the screen - they're just too easy to get at.
The principal issues are access, noise and cooling.
Access is probably the most difficult, where projectors are mounted at high level. Even in this circumstance, we try to make the enclosure big and strong enough to climb up into it and at least to be able to 'crab' or crawl around up there. Not always possible, of course. We also try to make the enclosure the full width of the auditorium - it looks better, means you can have the access hatch over an aisle and well away from the noise producing equipment, which helps. (Getting large pieces of kit in and out is no fun, it must be said!)
Cooling - you can't skimp here; vent lamphouse exhaust to the outside world if you can, obviously. Use a HVAC engineer you trust, and remember that it takes - perversely - more power to cool a small enclosure than a large one (within limits).
Noise - you just have to treat the enclosure as a 'miniature room' and build it to the same standard.
Is it cheaper? No, probably not. But there are other advantages - we got plenty of extra leg room without losing too many seats by demolishing the projection rooms in the conversion. One of the new builds just couldn't have happened if we'd had proper projection rooms - we tend to specialise in taking over old buildings and renovating them into cinemas.
Is it the right solution in every situation? No. We're building a cinema with a multiplex style mezzanine floor late next year, because in this case it works better.
One day I'll get round to uploading a bunch of photos...
