Building my first gaming PC budget $2000 suggestions?

Hello Phantom, assuming  you wanted to stay intel instead of swapping to Ryzen I put together a build for you that comes to 1992 bucks pre tax.  But I left some wiggle room in selecting a pretty beefy 360 AIO and getting a 1tb nvme drive as well as a 2tb spinning drive for storage.  All of which could be toned down to bring the price down to something closer to 1850 to allow for a windows key or for tax to not take you as far over 2k.  I also put you on the newest intel 10th gen because for 50$ more can get you what is essentially a 9900k in the new 17-10700k as well as a wifi z490 mobo.  Kept the case because you had a really solid choice in the lancool 2.  Hope this helps with your choices and have fun building.

When it comes to SSDs, Samsung is generally considered to be the "best" manufacturer, but realistically any of the SSDs will perform extremely similar. The Inland SSDs are perfectly good and considering that they're usually a fair bit cheaper than the Samsung, that's the direction I'd personally go. 

As for power supplies, there's a pretty wide variety of good power supplies available you can choose from. EVGA's Supernova Series and the Seasonic Focus series of power supplies are both good options, among others. We actually have a guide on how to choose a power supply here: https://community.microcenter.com/discussion/2872/how-to-choose-your-parts-part-5-the-power-supply

I think it'd be worthwhile to read through. I'm not familiar with the power supply the TheITDad listed in his build, but it appears it's not a pwoer supply we carry anymore.
