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.
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.
