I stumbled across the above site myself and was extremely impressed with the effort and images. I believe I was trying to verify what deck the main computer core was on and having a hard time placing it based on our current SIM Guide at the Academy.
There are some differences between these specs and what we had in our SIM Guide, but not having actually watched much of the Enterprise series (yes, I admit, I'm just an Enterprise nerd, not an Enterprise geek

) I'm not sure what differences, if any, deserve to be labeled as critically important to worry about.
I'm usually more worried that anything we write as engineers is at least physically believable.
