The integrated gpu of either i5 or i7 will suffice for anything except gaming.
For that, you need a suitably strong discrete graphics card.
You indicated that you have a gpu.
What is the make/model?
Do you have any other parts?
I note that neither of the options includes an OS>
Have you considered that?
Looking at the cases, it seems to me that they are deficient in cooling capability which is important if you will be using a strong graphics card.
My inclination is that I would not buy either unless you are incapable of assembling a pc yourself.
I did link above to a Greek site that's allows component choices and offers free assembly.
Have a quick look, I picked him a ryzen 2600x, a good B450 board, 16gb ddr 3200 ram,a fairly budget patriot 480gb ssd, a cooler master mb600 case with 2 x 140mm intakes and a 120mm exhaust and a cx550 psu.
Comes in at a touch over €500 I clouding assembly + delivery charges.
Seems a very good deal although I'm not familiar with the actual site.
They do have decent reviews though.
Obviously this relies on having a gpu (even an old one) to hand.
