A refurbished desktop computer is basically a brand new PC which has had work done to it. For example, say you buy a desktop PC and there is a hardware fault and you return it to the manufacturer.
The manufacturer would then fix the fault and run a series of tests on the computer until it is working like new again.
Then the computer is put back on the market for a lower price than new. That is what a refurbished computer is.
The advantage of buying a refurbished PC is that you don't have to worry about the machine having any hardware faults as it has been put through lots of testing, and any initial faults with the PC have been corrected.
Perhaps an even bigger advantage for you is the cost. Since the computer isn't considered brand new anymore, the manufacturer will sell it for less. So you can save quite a bit of money by purchasing a refurbished PC.
The disadvantage of buying refurbished means that you won't be completely up-to-date on the very latest hardware technology, but to most people this will hardly matter. Refurbished desktop computers are usually between 3 to 6 months old, and to the majority of computer users that isn't old at all.
Only the most dedicated of gamers and high-end PC users would need to keep their system updated with the very latest in hardware.
So is a refurbished computer for you? Let's just say that if you're looking to buy a new computer it would be wise to consider getting a refurbished one if you have a tight budget and want to get the most bang for your buck.
When shopping for a refurbished PC, make sure to find out about the warranty, return policy, and also compare the price with what you would be paying if the system was brand new.
In some cases you may find that you're not saving enough money by buying refurbished, so you'd be better off just buying new.
On the other hand, if you're looking to build a custom computer then there is the option of buying refurbished components which will work out even cheaper.
