I'm just throwing out numbers here, but if it was me I wouldn't go lower than...
$45 for the console itself
$5 per controller and memory card ($45)
$7.50 per game (x98=$735, or x100=$750 if you if you want to count the Resident Evil pack as three games)

So $840 if you priced it like that.

Now... if you jacked up the price and managed to get $20 per game, you're looking at $2,090. Not likely, since higher prices mean less willing buyers, but not absolutely impossible.
I'd say $5 per game and $30 for the console is a steal... shouldn't go any less than $575 at a minimum, I'd say.
Of course, I'd have to recommend going to eBay to search for the highest reasonable prices to charge per item. My random numbers are probably way off.
