Sorry to hear about your loss :cry:
But it does give you an excuse to buy the much better A1200. You can even buy a new old stock one from Amigakit.com. Plenty of used ones for sale on ebay and the like if you need to keep cost low. Only consider an A600 if either you want something small or you find one much cheaper than an A1200.
The parts you mention all have some value, I'd be interested in the keyboard myself if it's not too yellowed.
