First PC build in 10 years! - Upgradeable Quiet+Modest Gaming PC - $700

What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.

I want to get back into PC gaming to prove to my son that consoles suck. Seriously though, I built my own water-cooled PC 10 years ago and I miss PC gaming, but I'm totally out of touch with the latest chips and mobos. I want a PC now that can run low-end FPS games ( Fortnite, Rust ) on low graphics settings (Ryzen video?) that I can upgrade with a graphics card in November/December to run Cyberpunk 2077. I'm assuming that the current high-end graphics cards will drop in price when AMD and NVidia release their next-gen cards in the fall.

I'm old, so my eyes are starting to drop frames on their own, so I'd like to be able to drive 1080p @ 144hz on Cyberpunk 2077 after the graphics card upgrade, so please include a value/value 144hz gaming monitor in the estimate.

Stretch goal: I'd like this to use this a Plex media server for the household as well, so it'll be on 24/7 in my office. A quiet build with a RAID capable motherboard would be sweet.

What is your maximum budget before rebates/shipping/taxes?

$700 without graphics card

When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.

ASAP

What, exactly, do you need included in the budget? (Tower/OS/monitor/keyboard/mouse/etc)

Tower/Windows 10/monitor/keyboard/mouse

Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?

US - midwest. 3 hour drive to Microcenter, so it would need to be worth it to do a road trip.

If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.

No existing parts

Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?

Not overclocking.

Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)

SSD, RAID ~4T storage

What type of network connectivity do you need? (Wired and/or WiFi) If WiFi is needed and you would like to find the fastest match for your wireless router, please list any specifics.

Wired

Do you have any specific case preferences (Size like ITX/microATX/mid-tower/full-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?

No preferences as long as it can hold SSD >= 2 drives.

Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?

Windows 10 - I guess I could use it unlicense if budget requires it

Extra info or particulars: Quiet as possible, and willing to do liquid cooling if it can be squeezed into budget.
