Idea Rack Mounted PC build - specifically for use with Movie Studio Platinum (maybe pro someday)

Anytime you make a forum post - you are literally asking for peoples opinions - I get it. So I go into this knowing that....
I am remodeling my basement space to be a small content studio. Audio production and video, both post production and live stream.
I also plan plan on doing the same work outside of my space (not so much with the post production, but live stream and audio work).
My intent is to build a computer in a 3u rack space, and 'attempt' to keep it as quiet as possible. Most of what I render goes to the small screen so 720 is fine and 1080 is great - but takes time on my current set up.
Later on, I will probably build a 4k-8k editor. But right now, 1080 is likely the ceiling 95% of the time. I also don't do a bunch of graphics and special effects.
SO - my question is, knowing that I won't have as much demand on the system as someone creating full length 4k content with loads of effects, I am looking for a robust, but lower power draw, lower heat, less fan noise kind of build.

I was still thinking on using the Ryzen 5 3600 with possibly a RX 580 or something like that, stuffed into a 3U short rack (300mm deep) so I can load it into a road case and take it off site.
I was also even considering a Ryzen 5 3400G (integrated graphics) into a 2U 250mm deep case. This option would be likely temporary, still used for remote audio and live stream. It would be 10 steps up from my current laptop - so I would be happy - but also know I would need to build another render machine down the road.

So, does anyone have any recommendations for a CPU with integrated graphics, or a CPU and GPU combo that 1) work really well with Vegas Movie Studio Platinum (currently 15 but will upgrade soon) and 2) would be lower power and hopefully result in a quieter machine (even though I would be stuffing it into a box inside of a box)?

Thanks for your advice on hardware that should work well with the chosen software

All versions of Vegas Pro and Vegas Movie Studio, work best with using a CPU and a dedicated Nvidia or AMD Radeon Graphics Card.
Integrated graphics is nowhere near as good as using a dedicated Graphics Card.
In fact, integrated graphics does not work properly with many Third Party FX and can cause problems with Vegas.
I have had countless people contact me with problems, and many times we discovered that it was the integrated graphics responsible for crashes.

So when looking for a CPU, I would forget about looking at CPUs with integrated graphics, unless you need it for another purpose.

As far as cooling goes, I cannot comment on the Ryzen 5 3600 because I've never used one.
The AMD Ryzen 5 3600X with Wraith Spire is the superior model, if you want to use stock cooling.
However, many enthusiasts online would probably recommend you use a 3rd Party Air cooling solution or an all in one Liquid Cooler.
Air Coolers can be very bulky if you are building in a small space.
Personally I am a fan of all in one Water Coolers.
In my own computer I am using a Corsair 100i, which has a water block, radiator and 2x fans.
What I like about this solution, is that it comes with Corsair Link software that you can use to control the fan speeds.
I have me fans running at low speeds on idle, but programmed to ramp up when the CPU is running at 100%.

In my experience, the noisiest component of most computers can be the fans for dedicated graphics card.
So before you buy an AMD Radeon or Nvidia graphics card, make sure to find a brand/model that has good quiet cooling.
Last year my GPU died, so I bought an Nvidia RTX 2060 for MSI.
I am extremely impressed how quiet the MSI branded fans are - super quiet when at idle.

Thank you.
Just trying to figure out how to fit it all into a 1u rack space.
This is a stop gap build and wouldn't be my 'forever' video editor. And, I don't really use any third party plugins. Just mixing multiple camera feeds.
Thanks

What are your thoughts on the Gigabyte Geforce GTX 1050 Ti 4GB GDDR5?
Thanks

Always buy the best model you can afford.
If you're doing multi-cam editing, a good GPU will make things much easier.
All versions of Vegas will work much better with the most powerful graphics card you can afford.
I recommend you check out reviews on YouTube, to get direct experience on the GTX 1050 Ti.

Again, The Doc has provided some great information.

I'll add to this, but based more on the "Mechanics" side of things.

From your first post, you mention a "3U" rack style case of about 300mm deep. That is small! The new nVidia RTX 3080 Founder's Edition length is 285mm, and it is short compared to the AIB versions (Asus, Asrock, MSI, Gigabyte, Palit, Inno3D, etc.).
Now, the GTX 1050 Ti may fit, but again, the case your are mentioning, still leaves very little space for cooling. So, something has to give: Performance, Speed, Weight, Noise...you get the idea.

And, if the case is small, AND you want to be able to use it for traveling, again, there are going to have to be compromises somewhere. A lighter case for travel, will now not have as much "bulk material" to help not only in dissipating heat away (aided by strategically placed heatsinks), or not provide the necessary rigidity for the components you want to place inside, poor sound isolation, etc.

Yes, you said you want this small and portable case, along with some fairly "PowerHouse" components, but until there are some breakthroughs in the industry, you are not going to win the battle against "The Laws of Physics and Heat". Good example: both the newer consoles coming later this year have really upped their "Internal" power, but the companies have also had to put all the Gaming Goodness into a larger container.

I am not trying to convince you to not pursue, but rather do. Just really take a "Hard Look" at your needs, the type of footage, turn-around, etc. (Overall workflow, I guess), and carefully choose. There are lots of reviews on components, you have to be the one to siphon out the "rhetoric and crap" though. You are doing the right thing in asking for advice for this, and you will get some great feedback here in the forums, but as with everything (Video editing at least) you are going to have to be Patient and do that "Due Diligence" Homework.

As a side to this, if you were going a True Server style 3U rack case, just look at some of the ones at NewEgg Server Chassis . If this is too big, at least now you have something to start "size-wise", then start working smaller!

Thank you - yep, I know that the size of the case isn't great. I'm actually looking at seeing if I can stuff a radiator in a portion of it.
oh, and the case will be inclosed in a small rack. I've attached the size that I work with now. It currently contains my mixer/interface, wireless units and some other components. I will likely get a slightly larger one to either haul some of these components and the computer - or get another 6U like this and put the computer in it, with a drawer or something for a touch screen monitor for the live aspects of the build - but then be able to plug it into the triple monitor desk at home for editing.

But I think you are right - I may just need to do a single rack space, very low power, basic computer for running my live rig, and have a lager, cooler, quieter rig at home in the studio. I was sort of hoping to bridge a gap between the two for a bit (using the 3400g with integrated graphics for example). Just looking for a step up from my current laptop. Rendering is an overnight process many times. But, it wasn't purchased with the idea of video editing in mind - so the fact that it does it at all is still a bonus.
Thanks!
