A number of posts have mentioned brands, but it’s very important to consider the line within the brand. Consumer-oriented lines from HP (Pavilion, Essential), Dell (Inspiron, Vostro), and Lenovo (Idea pad, Legion) are absolutely terrible. Plastic everything, difficult/impossible repairs, no upgrades, etc. Every corner that can be cut, has.
Instead, look to the enterprise lines. Lenovo Thinkpad (my preference)/Think centre, Dell Latitude/Precision, HP Elitebook. I usually find the older ones (3-5 years old) that are off-least after enterprises are done with them, do a minor upgrade, and I’m good to go for a long time. Obviously that will depend on your needs, skill set, and desires.
