Foxy2013 :
Ok i am pretty confident building a pc by following online tutorials but my parents who are paying for it think that it would be easy to mess up and loosing money.
Can you explain to my parents that it is not hard.
Il show this to them.
Honestly, I'm a little torn on this one. I've built my own PCs for about 15 years now, and even when I first started it was surprisingly easy. (I imagine it'd be easier to build your first rig nowadays, what with youtube tutorials and more consistent hardware standards and better chassis designs and whatnot.)
That said, I was about 20 years old when I started. I wasn't living with my parents. I don't know how old you are, and although I have every confidence that (for example) a 15-year-old kid
could build a PC, I'm not sure I'd be eager to pay for him to try. In
principle, the task is pretty simple -- not much more difficult than assembling, say, a child's bicycle on Christmas Day. As long as you're careful, everything will fit together just fine.
But you might get a dud part, which would lead to your having to troubleshoot the problem, remove the part, send it back to the manufacturer, and wait for a replacement. Or worse, you might install something incorrectly, perhaps damaging the part in the process.
Then again, one of the perks of building your own is that you have fine-tune control over the components. You have individual warranties on all of them (in many cases, multi-year warranties); if you have a problem, chances are you'll get better service from the component manufacturer than you would from the Dells of the world. And it won't cost you anything to buy that warranty service.
Which brings us to the biggest perk of all: you will pay less, and get significantly more, if you build your own rig. You will have access to higher-quality (and thus, generally speaking, longer-lasting) components, even down to the power supply.
The downside, as before, is that you're on your own, but that's not really a disadvantage as long as you're competent. I can almost guarantee that a reasonably intelligent layman with access to google can troubleshoot computer problems better than the phone jockeys at a generic tech-support desk ("Is the computer plugged in?" Why yes, yes it is.)
The main hurdle is in the first month or so of the system's life. Any inherent flaws in your parts will tend to make themselves known fairly quickly. Once they've demonstrated that they work correctly, computer parts generally last a very long time given bare-minimum maintenance (ensuring that heat isn't a problem and so on).
Whatever your parents decide, I wish you luck!
