Low cost, low Power, upgradable PC build?

Hey guys, I'm looking to build a pc for the upcomming game generation.
I am currently running a HP dv6 Laptop, but I've been having some overheating problems.
It has a core i5, and a AMD Radeon HD 6700M Series gpu,
I can run bf3 on high at around 25fps, and that's ok for me,
but I'm looking to go to a deticated gaming PC,

I plan on making it like a c*nsole, so it will only be used for games,
and I'll be installing windows 7 lite to boost the speed (less background stuff)

but cost will be an issue, I plan on building it over the summer,
and  I plan to have the basic componet bough first, then get upgrades over time,

such as buy case, mobo, (a bit of ram), 1tb hard drive, cpu (maybe integrated gpu??)

and then later buy: deticated grapics card, more ram, ssd, more usb ports.

basicly I want to have a baisic PC I can add stuff to later on,

Grapics arn't a huge deal for me,
so starting out playing game at 25fps on med. is ok, (I'll be getting a detticated card later)

but having it low power would be a big plus.


So is this a good Idea? or would I be better off, saving up, and buying it all at once?
(also some product suggestions would be nice :D )  

that'd be a great idea. Would anyone like to take up this challenge? i'm thinking a10 apu and then get a 7950 later? and steal a hard drive from a playstation that why you don't have to buy one NOW and you can get the ssd now and get a 1 tb drive later.

Also may i recommend a 2 TB drive i've used up 1.5TB of my 2 TB drive.

Try this. ~300W once you've got everything. http://pcpartpicker.com/p/VUKk

and how about an amd build. http://pcpartpicker.com/p/VUKk

Budget?

 

For low budget and power go with an i3-3220.  But you'll have to buy a GPU if you want to game (Intel integrated graphics suck all the D)  Also look at an AMD A10 (consumes more power but you'll be able to get by for a while without a GPU)

What about this? http://pcpartpicker.com/p/W0iR

If Power consumption really is an issue go Nvidia for the gpu and possibly intel for the cpu

If you are going to be upgrading later i suggest that you buy a power supply that can handle your final build, to avoid buying two.

Good upgradabilitly  http://pcpartpicker.com/p/W18J

for the starting budget, I was thinking about $400-600,
What  kind of mother board would you suggest?
I'm thinking about going with an i5 for the cpu,  would that use significantly less power then the i7?
or is is not much diffrent? 

sounds like a good idea!

Ok, so I took a look at what you all suggested, and looked at similar products,

Here's what I think I'll go with:

(maybe an SSD, and a second bigger harddrive?)

Would that be an ok setup?
Probably not as low poweras I wanted, but it should not be super power hungry correct?
