I asked a question here and I was told to create another question asking for a mainboard recommendation.
So far the parts I have in my Amazon Cart are the following:

• The Ryzen 7 1950X (16-core, "Threadripper") (I don't know wether I should also purchase the liquid cooler)

Anyways though if there's a Mainboard recommendation that fits my required needs it'd be amazing to get some help, thanks!

The requirements established in the other Q&A:

• Must feature one sTR4 (the threadripper-) socket
• Support for 2x PCIe 3.0 x16 is required
• Support for at least 2 SATA-3 drives and an PCIe NVMe SSD
• Support for at least 4 RAM sticks and at least 32GB total
• Price should be 300 USD or less on amazon.com
• The mainboard should also not feature known spacing issues with 3rd-party coolers (don't need to research hard on that one)
• As the case isn't picked (yet) any standard desktop format is acceptable

It is preferable to make good use of the budget and get a durable mainboard over the cheapest possible fitting the requirements.
