Will this graphics card fit my PC?

First time asker!
I'm looking to install a graphics card in a work PC that I have lying around the house. I've checked out several graphics cards and I think I'm going to buy this one: http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gtx-760/specifications
However, I'm a complete noob when it comes to PC components and I'm not sure what PCI bus my PC has, or whether or not the graphics card will actually be compatible.
The motherboard is a Lenovo Intel Q45/Q43 (ICH10) model. Having a search online - I'm led to believe that this is a PCI-E bus?
The graphics card is a PCI Express 3.0, so would this be compatible?
I have attached a screenshot to help.
Thanks in advance!Will this graphics card fit my PC - 1

If the case can hold a card up to 30cm then it will hold any card. But however, you have a micro atx motherboard and if I can remember right that's if the motherboard is in the original case, it will only hold one up to 15 or 20cm. Do some measurements and make sore theirs no heat sinks or stuff in the way or it won't fit or it could even damage the card or the computer itself.

Assuming it fits in your case and that you have ample power to power it, yes, the long black lane there's PCI-E x16

Does your system has more than 500W power supply? If yes, then yes it should work. You can find graphics cards here
