well with  all that free time why not DIY build your own PC.

find a case first. (omg some great ones exists for sure 10x better cooling ! and longer lasting trouble free PC and  with huge fans and the magic, speed controls super quite.

then pop in a new ASUS.com Z370 or better "prime"

and build your own PC,  even learn that so you can do upgrades all by your self. etc, etc.....

never by any PC with ODD BALL CASES< (that look silly are are) stick to ATX spec. and win.!

@josemackinson :

Congrats on your upcoming retirement. Have you been consistently been on console gaming port and now looking to shift to PC gaming? Or have you been on a hiatus from gaming like yours truly.

I stopped serious gaming about 12 years ago and last year bought both a gaming PC and a console (Nintendo Switch). I realized I lost my ability to grind levels (after dropping $$ on RPGs on Steam), hand-eye coordination (so long Zelda), and found myself reduced to simplistic candy crushing smartphone games. So now instead of gaming, I just build gaming PCs (the irony ) and assemble Ikea furniture for a man-cave that I surf the Internet on an iPad in. 

Area 51 models are no longer sold.

I would Recommend XPS 8930.

Aurora Models are the only other models still sold.

Absolutely DO NOT recommend the G5 series.

You can find previously used models on amazon

Aurora's are nice for a pre-built. Minimum specs.

Intel i7 processor
16gb RAM
SSD 512gb PCIe/NVMe (as bootable C-Drive)
Nvidia RTX-2070
Liquid-Cooler for CPU
850w Power-Supply
Windows-10 Pro

I suggest no 3.5-inch spinning-platter hard-drives. Not only are they generally lame (loud, hot, unreliable, power-hungry) ... the way they are mounted in these Aurora cases, they significantly block upper airflow. If you need more drives, use 2.5-inch SATA SSD's (in provided bottom mounts). Also, no Optane non-sense.

And I do other things on my computers than just gaming, so I prefer an (IPS-panel) monitor like a Dell UltraSharp over a (TN-panel) "gaming monitor". Now-days, most people prefer a 27-incher or bigger.

Edit: I don't really do AMD these days, but it should be fine to substitute AMD equivalents for main-processor and video-card if that is what you prefer. But if you do that, you also get a different motherboard.
