Shood i buy a PC from my friends dad at a good price?

As the title say

its a 760 msi Geforce GTX 760 4GB TwinFrozr Gaming-series ( he bought it for 3 days ago )

and a amd X 4 965 owerclocked to 3.9 GHz normaly it is 3.4 GHz

and a 120 gb SSD

and a 500 gb HDD

and the chassi is a mid tower Cooler master Haf

and 8 gb off RAM   

and i don't now what the PSU is for W it might be 750W don't know 

and i get a 27 inch monitor

 

all this for 6000 Swedish Krownes (Kr) and the GPU costs 2600 Kr and the screen 1000-1500 Kr

7 Kr is one dollar $ so it will be around 857 $ butt in Sweden we have much higher taxes then USA have so
