Gaming PC under £300 that can run Minecraft well?

Anything with an A8 amd apu or higher will do fine with just minecraft… But really, save up man, gaming under 300 is a nightmare filled with compromise, at least save up to around 500-700 then you can be taken seriously.
if you really must though I would recommend scouring eBay, watching many $300 build videos on Youtube and keeping an open mind…

300 isn't very much if you want a good gaming pc. The cpu alone in my computer costed me 200$. Minecraft can actually be a difficult game to run. To have a great gaming experience, I recommend saving up. :/
