That is fine for recording minecraft!
Just a few pointers:
Definitely get at least 8gb of 1600Mhz Ram, you'll need it
If anything, go cheaper! If all your doing is recording minecraft id go for an hd 7770 or gtx 650ti.
i5 3570k is a great cpu, I'm using one right now
Might want to go for a 500w psu, just to be safe. Also make sure you go expensive on the psu, its the one part you don't want to have breaking on you! Also even though it says 430W, if its a cheap psu most likely it wont actually be 430W.
Also a 1tb would be advisable if you are recording games
