I was just giving an example, you'll find the difference increasing exponentially with bigger cases. The idea is the same for all components, and in the end you'll find yourself saving 400-500 riyals which you could invest into an SSD.. or some meth. :p

@Mr.S, this is a rare occasion, but it could happen. This is one of the few downsides to buying online, however as long as you're buying from a reputable seller you should be fine. If you buy and ship from Amazon, they cover shipping back for RMAs. The only problem is that items takes ~2 weeks to ship so you'll only have 2 weeks before the returning period ends. Although it should be enough to determine if everything is in good condition or if you have a DOA or something.
