Cheapest stuff I've been able to find so far:
~$16 for 64MB of RAM
~$15 for 3GB harddisk
~$1.5 for HDD cable
Beside that you'll need at least to reprogram
it's internal FLASH, and to modify it's board
in order to enable it to address up to 64MB
of RAM. As is it can only address 16MB,
that's not enough, at least for me, and, as
I have seen, this modification is nontrivial,
if you do not have good experience in
soldering.
