Are these the one who have dual graphics?
Can I remove one graphics card and put ssd ?
This is the single gt650m. You can buy the extra graphics card.
If you want more storage, there is an accessory for adding more drive space in the ultrabay
But it might be cheaper from the accessories page when you configure the Y500.
You also should be able to replace the hdd with a ssd, and you might be able to put in an msata ssd, and if you can put in an msata ssd, you should be able to configure it as a boot drive. I am not sure if buying a Y500 without a caching msata ssd means you get a motherboard without an msata slot.
