Is this desktop upgradable?

Is the HP s5150t an upgradable pc, where I can add more memory and a better graphics card? Thanks.
Im planning on buying it basic, and upgrading the memory and graphics card. I chose it with:

Genuine Windows Vista Home Premium with Service Pack 1 (64-bit)
• Intel(R) Core(TM) 2 Quad processor Q8200 [2.33GHz, 4MB L2, 1333MHz FSB]
• 6GB DDR3-1066MHz SDRAM [3 DIMMs]
• 640GB 7200 rpm SATA 3Gb/s hard drive from 500GB
• 512MB NVIDIA GeForce G210 [DVI, HDMI, VGA adapter]

PS> I know building a computer is much better, its just unfortunately not an option for me , so i just want to upgrade if i can

You should be able to install more ram. For now you shouldn't need more than 4gigs, but the mobo should be able to take more.

You have a socket 775 quad core. You should be able to use most s775 chips out there. The Q8200 isn't a very good quad and an upgrade to a Q9550 would be good.

The biggest factor other than those would be your video card. Does your pc have a pci express x16 slot? Take off the side panel and check. It will look something like this:

If it does then that means you can upgrade to a real video card. However getting a modern video card will probably also mean you need a new power supply as OEMs really like to cut corners there.
