Hi There
If you are going to use a signal direct from your proccesor then a slave amp like the MF450 or MF300 would be ideal, bear in mind though that the MF450 has a fan that is on all the time which will be heard during quite periods.
I would personaly go for a completed panel (Not because I work for BK), as this is a far easier and prettier way of making what would eventualy end up looking like a professional piece of kit.
As for cabinet designs try Win Isd for some ideas, it can be found here
