Oh my...There's 19 cm from the shroud to the case, the EVGA Geforce GT 740 is 17.5 cm long.
So i think it should fit, except that the slots where the end of the graphics card goes looks too small.
I remember seeing there were adapters to make the ends smaller what were the name for those?
I didn't realize that was a slim computer case as well..
You need to find a 'low profile' video card. They come with two brackets, one for standard, and another for slim cases.
The power supply you found most likely will not fit either, as it needs to be a 'slim' power supply.
The only other solution is a transplant from one case to another... but, ideally, you should find a low profile video card and install that... there are no adaptors to use regular cards in a slim pc if they are too big..
