Intel i3-9100t now provided by default on Minifree's Libreboot 3050 Micro: https://minifree.org/product/libreboot-3050-micro.html
It provides a ~20% speed boost over the previous i5-6500t, and also comes with Intel UHD 630 graphics (instead of HD 530 like before). Libreboot supports retrofitting these newer CPUs in the 3050 Micro, unlike in Dell's firmware.
Libreboot replaces proprietary BIOS/UEFI. Based on coreboot. More secure.
I also offer RAID1 now. (two SSDs).
I'm Libreboot's founder and lead dev. Sales fund my work.
