The passives are all pretty generic, as are the LDOs.. there's probably replacement parts for some of them anyway.

You can play with the value of R2 a bit if you want to mess with under/overclocking (change crystal X1).

You can probably combine a few more of these parts - e.g. C8 and C9, C2+ and C4+.

Important note from the schematic: All components should be rated 105°C or above.

Sourcing the BitFury chip will be your biggest hurdle, but have a look at the marketplace and e-bay.. there's full BitFury blades from which you can salvage them if you can't find a direct source of chips (can always post a WTB in the marketplace as well.. there's bound to be some still laying around).
