you should put the prices of each component into the list.. would help see where the budget is going.

from the looks of it though, looks pretty good for the price.

Heres another build you could try for a bit over $400

A bit more expensive than your build but you can run a full atx motherboard instead of a micro atx which will give you more options and better upgrading choices in the future. No use running an APU if you were gonna get a gpu as well but  if you wanted a really cheap video card maybe a DIAMOND 6450PE31GSB AMD Radeon HD 6450 1GB GDDR3 SDRAM PCI Express x16 Video Card http://www.newegg.com/Product/Product.aspx?Item=N82E16814103227 $45.99.

Well, not that I know much about motherboards and stuff, but since jesison2 made something above 400 dollars, it is too expensive as Brandon tries to build a pc under $400... 😀

I feel so poor and noobish when it comes to hardware and pc building

I found a build-your-own pc kit. It's a little pricey($481 on sale w/o monitor), but it has 8gb ram, 500gb hard drive, and a quad-core processor.
http://www.cpusolutions.com/store/pc/AM3+-FX-4100-Quad-Core-3-6GHz-Customizable-DIY-PC-176p3241.htm . From the link you can also click customize and choose some less pricey options to put it in your budget, but from what I can see on the site, this PC is pretty nice for a little under $500.

My build was only $17 above brandons budget not muchhh

If you aren't in a rush to buy, then I wouldn't buy, just wait it out longer and try get some more money to put towards it, look out for bargain deals on parts and see what is possible to build around it at the time.

Personally I think trying to squeeze in a lcd display is tough for the budget, but if you are, then I'd probably go with trying to get a better display even if its refurbished lcd. As outside of gaming and the need to get an lcd with low response time like 5ms and below you will want a decent screen with a resolution that is better for when you got money to upgrade some components ( 1920x1080 being the ideal)

Really a balance and compromise, but I'd try to get at least in something that can be utilized in the long run.

Also if you go with the APU-AMD A10-5800K  and going to be using the apu on it for a while until you get dedicated graphics card, then its def worth trying to get slighty faster memory like...

$32.99
Crucial Ballistix 4GB 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model BLT4G3D1869DT1TX0

As the cpu/apu will be using system memory, and having your system memory at ddr1600 (at minimum) and above will result in squeezing out some better fps performance..

Anyway here is my build..

CPU
$130
6core AMD FX-6300 .. good cpu performance for a bit of future proofing (its also 95wat )

  (though I honestly wouldn't buy it without checking everything would actually all work together as I stick with nvidia and intel myself and not familiar with the amd/motherboard side of things )

Without an lcd screen though, but I already said I think would be better to save up some more.

also saw this...

460gtx at $80 is a v.good deal not to mention it beats the amd/ati equivalents at those range of prices.. its also nvidia so you got better driver support not only for games but also production software.

The problem with that is, theres not any good cable management.
