I'm doing that right now. Though I don't know what the finished product will be exactly. I've got all winter to put it together. This is what's been decided on so far, and most has already been bought.

Frame - TST Sandvik 56 cm Titanium Frame ($495.00)
Fork - Reynolds Ouzo Pro ($239.00)
Crank - Truvativ Rouleur 175mm Crank ($149.95)
BB - Truvativ Gigapipe Team SL Bottom Bracket ($43.00)
Wheelset - Mavic Ksyrium Elite ($350.00)
Shifters - Campagnolo Record Ergopower ($200.00)

That's so far. The rest will come as I find deals. I'm going with a mix of Chorus and Record for a drivetrain (depending on the best deals to be found). Have no clue as to saddle, bars, stem, seatpost, pedals, etc...

All above prices were for new equipment also. Just gotta look around, and be patient (though that's extremely difficult).
