WTT/WTB: SGI IP59 quad-processor CPU board

Does anyone have this, willing to sell or --- more ideally, for me --- willing to trade a SGI IP59 quad-processor CPU/node- board? (P/N: 030-1989-003) I have several (non-SGI) systems of interest, Alphas (PWS 500au's and DS10s), but also Sun SPARCs (e.g. Ultra 10) and also at least one HP Integrity rx2620 "Montecito" (largely maxed out, with 24 Gbytes RAM) to trade. All of the above are max'ed out, in terms of 'specs' & configurations, plus there are many (PCI, PCI-X, AGP, etc.) options available. I also have an IP53 dual-processor CPU/node-board, as a possible 'replacement' (in case an IP59 board would have to be removed from a working system) and may even have a quad-processor one (i.e. the one I currently have installed). I'd also like to emphasize, to avoid confusion, that these are things I have to offer. Not so much things I'd like (or deem sensible) to trade 1:1. The reason I'm looking for this part, as well as other parts, is because I'm trying to get as much out of my system as possible, as I'm working on my portfolio as a graphic designer. Either way, please don't hesitate to contact me. I'm open to ideas and offers. Thanks in advance. - MG
