My advice would be to go with 8GB of RAM, rather than 4GB. It'd give you a lot more scope for gaming, especially with newer titles.
Best to go with 2x 4GB sticks, rather than a single 8GB stick.

As for motherboard brand, I don't see a problem with ASRock. We could list our preferences for brands, but the best thing to do is to look at what you aim to do with your PC and then look at the Mobo specs (and any reviews describing it's reliability).

If you're looking for a basic gaming machine, then it is worth considering these when looking for a motherboard:

• What size or 'form factor' motherboard do you want? Mainstream motherboards typically come in ATX, mATX and mITX.
  
  

1. ATX is what most would consider a 'normal' sized motherboard. Genreally 4 slots for RAM, has more PCIe slots for adding extra cards.
   
2. mATX (micro ATX) is the smaller version of ATX. they tend to be cheaper and at the basic to mid level of gaming, it makes no difference for gaming performance. They usually have fewer slots for RAM (the lower priced ones tend to have 2 slots for RAM, which is generally enough)
   
3. mITX is similar to mATX. prices are similar and they're about the same size. Their design is slighly different, though and you may need to find a specific case to keep it in. It is my understanding that many ATX cases may not accommodate for mITX.
   
4. Good thing about mITX and mATX is that they will fit in small cases, whereas normal ATX is too big to do so comfortably.
   
   

• ensure it has at least 1 x16 PCIe 2.0 slot (which pretty much all current motherboards have) for your graphics card.
  
• Also make sure it has the right socket for your CPU. The CPU you picked is great! But it needs a motherboard with the right socket, which would be an 1150 motherboard. Here is a solid example.
  
• If you're interesting in overclocking, then you'll want to pick a motherboard which allows overclocking. For the 1150 chipset, you'd have to find a motherboard of the Z87 or Z97 type. If you're not interested in overclocking then any 1150 motherboard type will do.
  
  Other than that, you appear to have a good build there! As for peripherals, anything will do. It's a matter of preference and what you can afford. You'll definitely want to find a good value 1080p monitor but as for the rest, I cannot really say. Good gaming gear is great, and really helps! But it's not always necessary, and it's easy to pick up better peripherals a little later down the line. I personally use this mouse on my gaming PC it's great value and it's served me well. Being able to change mouse sensitivity on the go by simply pressing the middle button is very useful.

OP lose the Razer stuff, if you want a mechanical keyboard they can be had for significantly less Exhibit A

You can also get a good enough mouse for cheaper, but if you really want a nice mouse $50 isnt too bad, but a good gaming mouse can be found for cheaper as well: see here

Also save some cash on the monitor, with something like this

use that money that you saved and get a better GPU, just wait a few months and get something like the RX 480.

After My experience with Cyborg mice I wouldn't touch those things with a ten foot pole, but with that being said a friend of mine has had his for about a year now and loves the thing. Mine the sensor went out after 3 Months and customer support was slow and really poor. So I just shelled out a few bucks and got a Zowie, although more expensive than that Cyborg, they are most defiantly worth the price. The tracking is flawless with 0 accel. Perfect for FPS games especially ! EDIT: Link to a great ZOWIE Mouse

I tend towards the more expensive units for better or worse, but my experiences with various Plantronics Gamecom series headsets have been quite positive. I really liked the Gamecom 780 I borrowed once and I'll bet the sub-$50 Gamecom 377 or 380 is worth it. Probably not the sure advice you want, but that's all I've got.

Additional options for consideration:

In my experience, Razer headsets look the best, but are much tighter on the head than others and generally sound over-bassy.

http://www.amazon.com/Logitech-G230-Stereo-Gaming-Headset/dp/B00BFOEY4I/

Logitech tends to have the most features and pretty decent sound, but are often finicky, especially with the microphone.

If you can splurge, this is as good as you can get without going custom: http://www.amazon.com/Sennheiser-HMD280-XQ-Dual-Sided-Closed-Back-Supercardioid/dp/B000Z76JBM/

To add about the wrist pad, get one that's about the height of your keyboard so your wrists won't fall into a weird angle causing stress, which I've noticed a lot of the stock wristpads that come with keyboards do cause your wrists to do.This one is pretty good. I got it on sale for about $6.

Another good one is this. They both sit about as high as a standard keyboard so you won't be causing any strain on your wrists.

A mouse-pad with a cushion may also help you, like this. It all comes down to preference though, as I like flat, large mousepads, but these can help reduce strain and keep your wrist straight.

Theoretically, they have similar hardware so you could do anything that you could do on a console, on a PC. As for answering your precise questions:

There are loads of options when it comes to cases, these may be annoying to build though - here's a link https://www.overclockers.co.uk/cases-and-modding/pc-cases/micro-itx-nuc/mini-itx-cases

I don't know about starting up the PC with a controller or booting into big picture but you could just leave the PC on with the controller(s) connected - have the monitor enter standby when the PC isn't being used and then just put it back on with the controller. Another option is using SteamOS, you could even dual boot it with windows if you want to use windows from time to time.

Very little PC equipment is CEC capable. Assuming your television is capable, you'd want an HDMI-CEC to USB bridge. Like this: http://www.amazon.co.uk/Pulse-Eight-P8-USBCECv1-USB-CEC-Adapter/dp/B005JU6LWM

Stretch that budget a little and get a good case. I have that case for a HTPC and while it does the job it is a nightmare to work in. You will thank me later, believe me.

Here is my recommendation

No it was cheaper then, this one looks like it would work too. http://smile.amazon.com/gp/product/B001CJOLBW/ref=s9_simh_gw_p23_d0_i3?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=1FY7FDE5G2Z3D4F9Q5NJ&pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846

Around that price just stick to a Corsair Builder Series.

Asus VN274H-P for the monitor, I have it, it works amazingly.
