I am debating whether to build my own or wait for valve.  For a living room unit that needs good 1080p support and a small form factor noise levels this is what I was thinking:

About $640 so far but I like the mATX form factor as it will work well on the tv stand beside the WiiU.

To get great 1080p (for the  LCD in the livingroom) and good sound I was planning on adding:

But I have questions about a few items.

The powersupply should be ample under load (130+280 for i5+760) but should I upsize it?

Is a non overclocked i5 in need of liquid cooling? The case will accomodate it but i am not sure it is worth it, and if so can you recomend one?

Is the repulic of gamers Maximus Vi impact board worth an extra $40?

I will be running a steam linux build and AMDs GPU linux drivers suck so I am not considering them. Plus 8gb of ram is tons when using linux (very little system overhead). I considered AMD processors but they are power hungry and run very hot... sweet price point though.

What are other people using for keyboards/game controllers on livingroom units?  This will be both WiFi and bluetooth compatible and I want to emulate a console type of build as much as possible.  Bluetooth keyboard is a given but are there any couch compatible mice ?

Power supply looks fine.

Stock cooler is fine for a non overclocked i5.

I can't find your specified motherboard, and therefore not sure which i5 you are looking at. However, you will be just fine with your current planned mobo, so not worth it.

If you have bluetooth then you can hook up a PS3 controller without a wire. X360 wireless PC controllers are popular too. And then there is also Logitech wired controllers. With whatever controller you pick, you should also keep a mice and keyboard near you, perhaps n the coffee table, for alternating use.

Finally, Asus announced today the Direct CU GTX 760 Mini. Like their 670 Mini, the 760 Mini would be perfect for your type of build.

On second thought, you might want to look into modular power supplies. They may suit you better.

With that said, if you want a nice compact case, check out Lian Li cases.

Thanks! This case will accommodate a full sized PS and even a titan card. The i5 I was getting for this was the i5-4670k good enough performance and low power drain. I am trying to keep the build under $1200 and an i7 is overkill.

I will check the compact cases you mentioned.
