On clusters we've built with Supermicro E7500 or E7501 chipset
motherboards (P4DPE, X5DPE), which I believe are roughly equivalent to
the Tyan S2723 in features and price, there's an IPMI/BMC option card
based on the Agilent BMC available. We've paid between $90 and $100 for
these cards, depending on volume.
I've not purchased Intel motherboards in quantity, but from doing a
quick web search, it looks like the incremental price between boards
without (SE7501CW2) and with (SE7501BR2) IPMI is no more than $150.
