I already have the Aerocool Strike-X Advance White Mid-Tower Gaming Case, as I bought that a couple of years ago but never actually got round to buying anything else. But I don't know where to start. I would like this PC to be able to run World of Warcraft and League Of Legends on highest settings with at least 60fps or 90fps if possible. Also to be able to run GTA 5 with high quality but as I'm not sure how powerful a PC needs to be to be able to do that, I'll be happy with one that can at least run it fast with decent settings. Thanks!
