it's definitely nothing fancy - an old dell latitude d630 business laptop from 2007 i had sitting around with windows xp professional sp3 installed. very late gen for win xp but it has really good support for it. it also has a dedicated graphics card and i put an ssd in it so it's not bad for gaming depending on the age of the game

intel core 2 duo t9500 @ 2.6GHz
nvidia quadro nvs 135m
4gb of ram

it's seen many, many lives at this point going back to my college days. now it's just for games ranging from 1996-ish through the mid-2000s. lots of road rash, marble blast gold, jazz jackrabbit 2, ut99 and unreal ed 1.0, halo, tons of stuff from childhood (including all my files from back then... 1999-2004), and most recently tes3 construction set
