Reddit mentions of Max Keyboard Cherry MX Rubber O-Ring Switch Dampeners 50A - 0.4mm Reduction (130pcs)

So let's cut right down to it and explain the parts:

• CPU: Intel quad-core, hyperthreaded CPU. This CPU will perform very well when playing any game, while streaming. Videos below will explain more why this CPU is more than good enough for your use. Got the H.264 codec which allows you to record and stream at very high quality.But this will give a hit on FPS.
  
• CPU Cooler: Review. Easy to install, silent, good looking CPU cooler. Will keep the Xeon more than cool enough.
  
• Motherboard: Black & red gaming motherboard. Got better on-board audio and a dedicated network chip to provide low latency when gaming.
  
• Memory: 16GB of RAM. Speeds don't matter, only capacity. 16GB is overkill for a gaming PC, but will be helpful when you're using a lot of programs at the same time.
  
• Storage: 240GB SSD for OS + all editing / streaming software. 2TB HDD for your game captures. Able to expand this later with 4 more HDDs.
  
• Video Card: Review. The best single core GPU on the market. Got Shadowplay, which is a feature where you can capture game play with, although not at a extremely high quality.
  
• Case: Review. Very awesome quality case and easy to work in. Given that it's $70, it's very good.
  
• Power Supply: Review. 5 year warranty, 80+ gold, semi-modular (so you only have to plug in the cables that you need and nothing more), semi-passive fan profile, 650W PSU from EVGA made by FSP. This is a very high quality PSU. Which will have no problem powering this system that will at most pull about 350-400W depending on how much you overclock the GPU.
  
• OS: Windows 10, remember that you need to have a USB stick of at least 4GB to install Windows. Also you need to have a PC with Windows on it to make use of this. If you're using XP you'll have to download the ISO file from the program and use Rufus to install the ISO on the USB flash drive.
  
• Monitor: 2560x1440p IPS monitor. You will absolutely love this monitor and the amazing image quality + size. You can simply record games at 1080p no problem. When you stream, you should also just stream at 1080p and use the downscale option in OBS. This will then record your whole screen and simply down scale it. So the viewers will see everything that you see. Same thing will happen for the recording.
  
• Capture card: Because you said that you don't want to have any loss in FPS while playing / recording games. This device is a very nice option to go for. This got a HDMI pass-through and will use the H.264 encoder to record or stream gameplay. Here is the product page. You simply connect this device with USB 3.0 to your PC, then you go out of your GPU into the device with HDMI and then out of the device into your monitor.

• Keyboard: Review. Mechanical keyboards are a lot better in terms of typing and durability compared to membrane. But they are louder.
  This is the Cherry MX red review and I went for the Cherry MX brown. The reds are perhaps even more silent once you've applied the O-rings. Not entirely sure about that. Here is a very good read about mechanical keyboards and especially a nice look at the different switches. I use MX browns personally and it's not silent at all, but it's far less loud compared to MX blues, that I've used previously.
  
• Mouse: Review. This is probably the best review of this mouse. There is an RGB version now, but it got a $30 premium.
  

• Webcam: Review. Pretty damn solid webcam for the price.
  

  
  

  Note: the total price is without the keyboard, mouse & webcam.

  Now I will also provide you with my standard list of videos to help you understand why I suggest these parts.
  

  Lastly I'll also provide you with a couple of great guides to help you build the PC.
  

  I have to post this in a reply to this post, since I went over the 10.000 character limitation reddit provides per post.

I've got the Cherry MX branded o-rings. I believe they're about a 50A hardness and mine are pretty thin only 1.5mm

These here look to be the same thing but rebranded and more expensive than what I paid.

https://www.amazon.com/Max-Keyboard-Cherry-Rubber-Dampeners/dp/B00E4MYDTY

I would say get a good quality Cherry MX Brown keyboard and put 2 sets of these o-rings in to reduce sound. https://www.amazon.com/dp/B00E4MYDTY/ref=psdc_12879431_t1_B00AZQ2OF8

Exact measurements would help but I would say the Deathadder, G403, EC1-A, or the to be released Rival 310

I use brown switches in my office with o-rings on the firmer side. I mainly put the o-rings on because I like how the browns feel when you bottom out with them better. No complaints from anyone in the office, definitely much quieter than blues.

Edit: These are the exact ones I have, though it looks like Amazon doesn't carry that brand now.

I use browns with O-ring (http://www.amazon.com/Max-Keyboard-Cherry-Rubber-Dampeners/dp/B00E4MYDTY/ref=sr_1_16?ie=UTF8&qid=1414552892&sr=8-16&keywords=o-ring)

I really doubt that the Rosewill will reduce travel by 0.4 mm with a 2mm O-ring. Probably closer to 1mm reduction (50% of space beneath actuation is gone).

I'm taking a look at the Max Keyboard O-rings on Amazon here which say they reduce travel by 0.4mm. You can do a scale photo with the O-ring on the stem - the Cherry MX stem is approximately 5mm across in life, and it's 2cm in the photo - the O-ring is measures at 0.6cm, so it's approximately 1.4-5 mm - giving approximately a 1mm gap.

In your quest to put the bottoming-out as close to the actuation as possible, please remember that Cherry themselves ballpark the actuation point at 2mm with a 30% above/below error rating - while in practice I don't think I've felt this much deviation in my fingers, it can exist. So you probably want to reduce the bottoming out by about 1.5 mm total at most - you don't want it just on the actuation, or it might not actuate at all unless you smash it so hard the O-ring deforms on the cross-bars and it'll hit that zone. It's a mechanical switch, so it's better to err on the side of caution and make the key go beneath the actuation point every time. The big O-ring from imsto should be just about right for you.

And as for feeling the difference - for people who bottom out their keys with clacks, even the 1.5 mm O-ring has an enormous difference because of how different it feels - from a clack with vibrations to thud with a give absorbing some force. I definitely notice my 1.5mm O-rings on my QFR, but I don't notice it so much on my Logitech, which uses a thinner and harder O-ring. For some people, even 1.5mm O-rings are a lot - that's why they pay for the thinner O-rings from WASD, so they lose as little of the mechanical bottoming-out feeling as possible.
