Way to go
I sort of did that with a $2600 laptop (the one I am currently on). although I didn't get it for free Officeworks couldn't sell it after a customer returned it for operating like a dog.
I noted it was a 3 gig P4 with only 256 meg ram.
They had it on their throw out discount pile and I kept checking on it every day for 3 weeks. then they had a brain explosion, they discounted it from $2300 to $1000.
I bought it and stuck in 512 meg ram. works a treat!
