No that one looks pretty solid, z77x ud3 and ud3h are great mobos, the only thing thats better is some other ones that are in the $130 range with good built in audio. Not sure how people make builds without the os... do they just torrent it? Maybe they just transfer it from their old computers•
Oh, and do you live near or can drive to a micro center? They have the 3570k on sale for $170-180 (believe its $175 but could be $170 or $180) and they have $50 off motherboards when you buy them with cpus. Sick deal. Also the 3770k is $230 there, so you could easily upgrade to that.
For gpu, if you buy at newegg you can find the 7850 for as cheap as even like $150-160 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814131473) and it comes with free tomb raider and bioshock infinite.
Or to spend a litte bit more you can get a 7870 for $220 ish (http://www.newegg.com/Product/Product.aspx?Item=N82E16814150604) still with those free games. Heck, if you sold the games you could probably get a 7950 for the same price :P
Another thing you can do is use an older case and cut out the optical drive, you really never use them anymore. I just have a usb one I use on all my computers (parents, brother, and my two)
