I can't make assumptions where OP lives. In my country there are quite some dealers who trade with refurbished business laptops or leasing returns. This is not the hottest new electronic shit on the market but mostly very affordable and durable business laptops which are easier to open, to repair or to exchange parts, e.g. when you need a bigger storage device in them.

You don't need the newest hottest stuff for big money, you can enjoy laptops that are built to last and do the job. Stay away from consumer laptops, some of them are a pain to open to replace RAM or storage. If you don't need the mobility aspect, then battery life might not be top priority either. Very common older business laptops sometimes still have some suppliers for the battery. Stay away from cheap battery crap, you don't want to risk to burn down your living space.
