If I was you build it yourself it's not that hard and you get a lot of flexibility
first off, move from League of Legends to Dota2 (free on steam) it is a little harder but is much better when you get in to it.
haha yayyy LoL players <3
but in all seriousness how is that PC i copied out a sec ago? bad or fine
Its good, but Rowcon is right, building it yourself wil be cheaper, and give you a lot of XP
