I think this sounds like a great project.
I had a couple of chilis and have some thoughts on improvements;
I'd like to see thicker PCBs and better heatsink mounting options, it was a bitch getting a CPU heatsink to fit the old boards. I would also like to see a full package option like techno-bit sells maybe excluding the boxed watercooler, finding heatsinks for mosfets and what not is very hard if you only have a couple, but bulk from china is rather easy.
