Well, i've got 2 spare 512Mb RAMs with the exact specification which i plucked out of my MacBook which should work for all laptops seeing it's a RAM.
Nanya (Apple) RAM 512MB DDR2 667 SO-DIMM (PC2-5300)
Anyone wants it, i'm selling it for a fiver each (Can't get a better deal than that i don't think!).
I would prefer to be paid via PayPal for those interested! Thanks
