Which PC build is best for ONLY MINECRAFT?

I only want to run and record Minecraft (POSSIBLY other low demanding games in the future) at 60fps and I don't mind lowering settings a little. Feel free to leave any other suggestions in the same price range or any changes I should make or anything I need to add.

First build, $200:
AMD A6-7400K 3.5GHz Dual-Core Processor
MSI A68HM-E33 Micro ATX FM2+ Motherboard
Pareema 4GB (1 x 4GB) DDR3-1600 Memory
Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Apex TX-381 MicroATX Mid Tower Case w/300W Power Supply

Second build, $300
AMD A8-7650K 3.3GHz Quad-Core Processor
Gigabyte GA-F2A68HM-DS2H Micro ATX FM2+ Motherboard
G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-2400 Memory
Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive
Rosewill FBM-01 MicroATX Mini Tower Case
EVGA 500W 80+ Certified ATX Power Supply

First one, everythings good to me… I'd get Apex SK-393-C case and a EVGA430B power supply…
actually a Case with Power supply is Rubbish.
