In the US I know NZXT and Xidax both have pretty decent prices. Cyberpower is super hit or miss on both construction quality and quality of parts they use. The best and cheapest option is to build your own, with youtube and websites like these there are countless guides on how.
In many countries, yes, but not recommended. 1. Overcharge 2. Limited choices
I will definitely recommend building your own. Budget? Country? Major usage?
