[Vic2702]

Budget (including currency): 2000 mexican peso

Country: Mexico 

Games, programs or workloads that it will be used for:  I'll be using ansys, solidworks, and playing fortnite and some worldwar z

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): hey, i wanna build my first pc, i have an old case (like windows 98 was the os it used) so i wanted to reuse it but i dont know if it matches with my setup, the list is: 

+ ASRock B450M PRO4

+ Ryzen 3 3200g

+2 sticks of hyperx fury black ddr4 2666MHz

+ Gigabyte nvme ssd 256gb

And im still trying to find a power supply

So, how do i know if i can use this old case?

If your case is that old from windows 98 you would be much better off getting a new case.
