Most if not all of the info you need to build the exact same brew system is in this thread. I know of a few people who have built a near exact clone of the system. The take away from my brewery project should be to make an improved or enhanced version, not just a parts list to shop with. Almost everything was parts ordered from standard brewing suppliers like Northern Brewer, Midwest brewing supplies, Brewers Hardware, and BrewTroller.
As I've said before much of my systems design is based on the idea that I had no year round access to running water and a drain. Therefore reusing the HERMS coil as a cooling device, and hence my plumbing designs, are all predicated on that.
I used a number of other parts, like compression fittings, tank level tubes, kegs as kettles, etc that I would not use again if I were building it new.
If I were building it from scratch I would do the electronics and most of the frame the same but use a higher quality SS strait walled kettle with a bottom drain if possible and all welded fittings. I would also use a standard counter flow chiller and might even look into rims or a mini kettle to do the HERMS heat control for the mash instead of an entire kettle.
I also looked into using a tankless water heater for a house as a hot water source that I could then fine tune with a RIMS system to brew faster.
The point is, much of the info I have is up here, and even still I would try to do what works best for you. On Google Sketcup 3d Warehouse their is an accurate 3D model of the brew system with all the dimensions you would need to build the frame.
I am considering selling my entire setup as I may soon not have the space to brew. Currently I do not have the time or cash to do so.
Here is a picture I am working on that I took of the brew system a few weeks ago.
