Well, this was an "interesting" read. After going through six pages of this thread a few things have struck me:
- There's an amazing number of people who have posted without reading. I'd be very surprised if the "client" here wasn't a business who is going to be using this for some sort of demonstration purpose. In that arena, $8K to $10K is not all that much for a machine that is essentially a money maker.
- I think you got some seriously good advice about looking at 6-core chips. When I read that I took it as 6-core i7s, but I think you should consider the Xeon chips as well. You appear to looking at raw processing power and have concerns about dependability, so why not get something enterprise class? With that budget you should be able to afford it.
- My only comment about your aesthetic choices (read case, mouse, and keyboard) are going to be along the lines of I hope that case is going to be hidden. For a build of this magnitude, I wouldn't want to see a HAF X unless the space had a very futuristic vide to it. If you don't already have them I might ask for photos of where this is going to be located and find out how much is going to be visible and what the overall aesthetic of the space is. If the HAF X is not a good match for the style, you might want to consider having something made. Again, you have the budget.
- I don't know those speakers, but I do know that without again knowing the space, choosing speakers may be difficult.
- About the projectors, you said you were projecting onto a cured screen, so I'm assuming the software that's going to drive the projectors will handle the deformations. Does the publisher of that product have any guidelines on choosing projectors? The ones that hang in the Board room at work are nice, but I wouldn't say that they'd produce an immersion experience, even if you had three of them projecting onto correctly shaped screens. (And the ones that you have listed seem kinda like the white version of cheap Board Room projectors.) You might want to consider something specifically designed for HT use.
It seems like a killer project, but I think you might want to really consider matching hardware specs with performance needs. Simply knowing that you want to create an "immersion" experience without knowing how the projection stream is going to be coming to you or what frame-rates are necessary, makes it hard to be more specific. I suspect you might be a little over on the GPU side, and perhaps a tad under on the projector side. I would also pay close attention to whether or not your box has to be visually part of the user experience, or whether it's a hidden tool.
In all these things the customer's spec should drive your choices; it is after all their dime (ok, I guess technically 80K to 100K dimes.)Edited by Florida_Dan - 10/30/11 at 2:33pm
