Dell now lets users configure the Alienware Aurora R15 gaming desktop with AMD's new Zen 4 processors. One can pair it with most Ampere and RDNA 2 graphics cards, but Ada Lovelace SKUs are restricted to the RTX 4090. One can buy it on January 5 starting at US$1,750. https://www.notebookcheck.net/Alienware-Aurora-R15-gaming-desktop-now-available-with-AMD-Ryzen-7000-processors.678427.0.html
That case is unnecessarily large for how little space is actually inside.
I would suggest you see Alienware reviews on Gamers Nexus YouTube site. This case is problematic and the system has many proprietary parts. Too expensive.
