A on the go computer

[Tankattack]

I move around a lot so I don't like moving my 25 pound beast of a pc. So I am wanting to build a small light weight pc that is more suited for moving. I want to keep it in the 500-600 dollar range but I could go higher if needed. My main game is dota 2, which doesn't take much to max it out. But I still want to be able to play most games on low or medium settings. If I can I would like to be able to play Battlefield 4. over 40 or so frames. The new nvidia gtx 750 looks pretty nice. Small and with decent power. Anyways just looking for some ideas. Also since this is a on the go computer the motherboard has to have wifi. Thanks in advance!


edit: This is just the tower. I got a copy of Windows 7 and I have monitors, keyboards, etc

Hey you should grab a Bitfenix Prodigy M Case. It's got handles and fits 320mm (12.5 inches) of graphic card in it's compact case with 120mm Rad x 2 capability. Its a micro ATX. Should be able to fix some decent hardware in that thing

Another idea for the case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811112407
Budget case (I liked the layout): http://www.newegg.com/Product/Product.aspx?Item=N82E16811237025
Very affordable, PSU is included (although not exactly top notch) and M-ATX which will help shed a few bucks compared to M-ITX and can handle full sized video. PSU can move 750/ 750TI + i3 perfectly, probably 65W i5 also, if the budget allows it.
I've thought about a similar very portable (LAN party) desktop machine, but haven't managed to compile a decent looking build with moderate budget so far...
Think about a gaming laptop, Lenovo's Y series are quite capable multimedia/moderate gaming machines for $700-800. The mobile version of 750 (860m) is expected to start appearing later this year in laptops and promises very good performance.
