A Thinkpad X200 - not wiped in 13 years (since installing Arch). Truly a frankenstein’s monster of a machine now. Hardware mods are so easy on this thing - I switched to an SSD probably 10 years ago, some RAM upgrades. Upgraded Wi-Fi card a few times (mostly based off mainline kernel driver support). Touchpad a couple times, keyboard at least the same. Keeping Arch running on this machine without wiping everything is the only think keeping my Linux skills sharp in the era of company-issued macs.
