Simple but small budget build

Feels weird writing one of these, since I haven't built something in a while. But here is the idea, I'm trying to build an extremely cheap computer, that is meant to be as small as possible, but still be able to game, do normal browsing and play videos (x264 10-bit, 1080p), and possibly do some video/photo editing. My inspiration for this build came from Linus's Scrapyard builds (https://www.youtube.com/watch?v=x1JA24KCAjE), that were damn cool. But I wanted to see what I could do with brand new parts, and I wanted it to replace my current secondary rig, which has served me for almost 8 years now, and has started to become more unstable than before (it already was an extremely stable pos, just more now). My other inspiration was Linus's insane small rig built in the SilverStone SG13 (https://www.youtube.com/watch?v=x1JA24KCAjE).

So here is what I've come up with: http://pcpartpicker.com/p/w3fWTW
Budget: As cheap as possible, 350 USD is about max though
Part list (you lazy people):
Pentium G3258
ASRock H81M-ITX Mini ITX
Vengeance 8GB
Crucial BX100 120GG and a 500GB HDD (or a 250GB 2.5" HDD, both salvaged from that secondary rig)
GTX 550 Ti (I already own this)
Silverston e SG13B
Corsair Builder 430W 80+ Bronze

P.S. I do have have a main rig, this is not meant to replace it. It's meant to act as a secondary low power rig.

I'd do this

Hmm, I did think of something like that. But the mobo that you are using is a Micro ATX, which (sadly) doesn't fit in a SG13.

And I couldn't find a way to justify the extra 40 bucks for the i3-4160. The only added advantage it had was an extra 2 hyperthreaded cores, but actually a lowered single thread performance.

Are your current existing parts included to your budget or can your budget be used on completely other stuff you don't have?

Ah yes, my current existing parts are not included in the budget.

I already have GPU, and HDDs. I have some RAM laying around, 8 GB total, 2 x 2GB and 1 x 4GB.

what will you be using it for? i mean, do you need 8GB of ram? you would throw in the two 2GB sticks and run a 32-bit OS. It would save you $50. i mean if you are using it as a web-surfing HTPC type of thing, 4GB is more than enough.

Good point... I don't own any 32-bit OSes, since all my isos are 64. But I should be fine.

Haha, the HTPC part made me think that HDD space is more important, so there is my updated build... Wifi might be inportant too, so there it is in the mobo.

yeah, you should. i mean, my livingroom pc is running 64-bit with 4GB. so you would be fine. I think the most i ever got to 4GB was with like 15 tabs open on chrome? lol
