What computer runs Minecraft lag free?

I'm wanting to build a custom gaming desktop for Minecraft, and making videos for youtube. I need to know what processor, memory(ram), motherboard, graphics card, hard drive, optical drive, power supply, and operating system i should get. What case should I get to make sure the parts stay cool.

Added (1). grimrpr6942 do those parts work together because i want to make sure before i buy them.

1. Any quad core or above cpu ( not apu)
2. At least 4GB ram but more the merrier
3. The motherboard that works with your cpu and ram
4. Any 2 gb ddr5 gpu that you want
5. Any hard drive
6. Any OD
7. Any psu that is above the wattage of your computer
8. Any os but mac

go to http://pcpartpicker.com/ to make your build to make sure it is compatible

Depends on your budget, to save some money, go with AMD.
CPU = AMD FX6300K $120
MB = Asus M5A99FX $125
Cooler = Hyper 212 EVO $30
RAM = G Skill ripjaw X 8GB (2x4GB) 1866mhz $85
GPU = XFX HD7870 $180
PSU = XFX ProSeries 750W 80+ Gold $120
HDD = Seagate Barracuda 1TB $60
This build comes to about $660, just add whatever case you want, DVD drive, and operating system.

Message me your price range. I can try to get the best thing for you. If your price range is under 400, then I can't help you. You need money to get a good computer.

This is better to buy pre built: http://www.newegg.com/...6883229437

and installing this power supply: http://www.newegg.com/...6817339020" class='ext_link'>http://www.newegg.com/...6817339020

(have it for my PC at a higher wattage)

its cheaper than the parts. If you go with what that guy posts there are a billion other things you will need that you don't know about, like hard drive mounting screws, thermal paste, sata cables, etc.

if you Really want to build your own there are some general modifications i would do. I will show you in a minute…

-edit- everything i can think of for a computer…
