I sure this has been asked a lot but I've been unable to get all the info about this together. I know this upgrade is not very cost effective but would never the less like to know what it would take to convert an old mac pro 1,1 to a 3,1. A new Logic Board, Power supply? Has anyone done this upgrade and what was the process?
Got a tip for us?

Sure someone's done it with pictures on this forum, though I would be tempted just to grab a 3,1.
Yep, quite an interesting read, actually. But for sure, probably cheaper to either Grab a 3,1 or upgrade your CPUs to the standard 2,1 config, with dual Quad 3.0GHz. I think they still outperform the 2.8 8 core 3,1 even though they're an earlier production model.
My maxed out 3,1 may possibly be available within 4-6 weeks if the 5,1 comes my way. Though if you're not in England, better still within driving distance of South London that may cost rather a lot in shipping cos my missus ever so considerately decided to let the kids have it as a play box while I was working away. It had eye holes cut out on every side and a big escape flap cut out. I laughed too much to get angry about it 
Great! This is what I was looking for. Looks like a lot of work and and about $450 in parts. It might not be worth the upgrade but good to know the process.
Thanks for the info.
No probs - from a purely fiscal view point the conversion makes no sense, even in these days of reasonable priced second user MP parts - the only way it makes any sense, is in a 'mountaineering', because it was there, and because I could, sort of way - just for the experience, as it were.
