I picked up a business class laptop over 10 years ago. HP, don't know if they still have it, had a web site with returned and/or refurbished equipment. You have to check it often, as they might only have one or two of the model with the features you want, but had great deals. Most stuff was still in factory sealed boxes, never opened.
I just stopped using the laptop, not because for any hardware issues. It did develop a battery that doesn't like to stay charged for long, but that is to be expected, and didn't hurt what I was using it for. This machine would come out with me on sound/lighting gigs, getting rough use, and has never failed. Still running XP on it.
It was not a model with encased with rubber bumpers and stuff like that, but the lid/screen was metal rather than plastic.
