[AdurnX]

What's the best PC under $400 for OW? (I dont need mouse, OS, kebyoard or monitor).
Btw I am from Czech Republic.

This is the best I can do for you, but I'm not sure what currency your money is in:

Overwatch is a very well optimised game and runs great on weaker hardware

A 4th gen i3 or better
8gb ram or more
Gtx 750 ti or better

And youd get 60fps solid at 1080p / medium

Spend just a bit more, this PC will run Overwatch on Epic pretty easily.

I realize I went with 500 GB, since your wish is to play only Overwatch, I thought that would still be enough. Overwatch takes very low space anyway.
