Hi,
I guess that looks about right, although some of the generic components can be found for cheaper than that. You might be able to shave off $100 or so...
Still an expensive lump though... and the main reason that I wouldn't get one - can't justify the best part of $2k on a hobby machine...
I'd (and this is just me!) prefer to invest my hard-earned wonga on a new x86 box to run Win 7 & Ubuntu! :-)
... and with the change, pick up some nice classic 68K Amiga gear...
Cheers,
Mike.
