Best PC Gaming tower to start building onto?

So basically, I'm a HUGE PC gamer! I mainly play minecraft as my favorite game! I'm looking for what PC I can buy and then add custom parts to! I'm looking for something along these lines;

Asus 64-Bit Processor (Tower)

And that s basically it, lol! I'm looking to find a PC I3 Motherboard as well. I'm looking for a newer model of the Asus 64-bit processor, 2015 models would be awesome! I will go 2014 if no 2015 look to "amazing"

Remember, I'm looking for a PC to start adding custom parts to, for GAMING. I plan on adding a PC i3 motherboard, and then going on from there. This is mainly for minecraft, I want speed, ram, and memory!

Future thanks!

Added (1). I will also be playing, Runescape, Skyrim, Fallout, and other games that need some major non-lag, and good graphics!

Uhmm.

First of all 'custom' parts is very strange. We all pick the parts we want to create a customized desktop, but the parts themselves are not 'custom'.

"Adding parts to." - This is not a good idea. For a desktop to work - it needs all the required parts: CPU, RAM, Video, HDD, Motherboard. Some people would like to start inexpensive and upgrade, but this does not work well. You have to replace the less-expensive parts with the better ones and at the end you have basically paid for 2 desktops to get 1 better performing desktop. Not a good idea for people on a budget.

"Asus 64-bit processor" - I was not aware that ASUS made CPU's. Are you talking about the motherboard?

Look - the gaming motherboards, cases and RAM are all nearly identical performing to non-gaming versions, but they add $$$. If you don't have the money - avoid the 'gaming' labeled parts.

The one exception to this - the video card. Gaming is all about the video card. Right now the GTX-970 is the best bang for the buck. The GTX-980ti can rival the frame rates of the Titan X.

MY ADVICE:

Go to PCPartPicker and create an account. Start creating builds. It will show you the best prices, give you a link you can share if you have questions, it will show Power usage and some compatibility checks as well.

Below is my often-suggested parts for a good gaming system:
