That one is a little bit out there. That board is probably $10K, and you need a $100K Tek Logic Analyzer to use it. :)
It's just a passive DIMM module with cables for each signal connection at the socket. I'm sure it's priced relatively high since it comes with coaxial cables for 8GHz timing analysis and was probably assembled by highly skilled elves. Someone could fab these however as a 2 sided pcb with only the SMBus signals for next to nothing in cost.
