M2453 300MHz: PPC 750, Blueberry or Tangerine
M2453 366MHz SE: PPC 750, Graphite
M6411 366MHz: PPC 750CX, FireWire, Indigo or Key Lime
M6411 466MHz SE: PPC 750CX, FireWire, Graphite or Key Lime
If one could hack a M2453's logic board into a M6411 case, you could have a Lime G4. (without FireWire)
@CC_333, the 366MHz SE model has a 750, so it should take a 7410 the same way the original 300MHz model does, but it doesn't have FireWire. (See above)
