Well... I recommend you to try an old Amiga 1200 . You will find a big surprise how this 20 Mhz machine it's highly responsive, and boots faster that any current machine with Windows 10/11. However, it would not look fancy to our current eyes.
I had this one: https://www.jaruzel.com/blog/amiga-500--fun-with-storage. The official Commodore one was much uglier and, from memory, only 20MB.
14 MHz !
