Re: What type of computer do you use...
My son and I built this desktop. It was interesting as it was my first but my son as built a few in the past.
What was my criteria for the build and should be the first question if doing it yourself. This can dictate the components used. In my case it was for photography so graphics cards came high on the list .
In the build first was the computer case, this had to have a good airflow as the cooler a computer runs the more efficient. So we choose one with a front back vents against one with a side vent. this should help better with air flow.
Next was the processor. Looking things up I did read that an I7 processor was better than an I5 for video work so that is what we went for. Apart from adding a 250GB SSd card and a HD card for memory also taking into consideration was how quiet it ran.
So fan change all round to run quite and at the same time a silent CD/DVD drive.
As the case came with plenty of USB3 and USB2 ports that wasn't a concern to upgrade.
At the same time boosted the Power unit to 750W to allow ample power for any future additions. RAM was also upgraded to 16 megabytes, far more than really needed but allows for several programs to run at once.
Moving on, by hand picking individual components and doing it ourselves (more my son than I) it allows us to know what exactly is the computer build and if things go wrong what and how to replace or upgrade.
Cost wise , if you could even buy the same shop wise,( which you can't as a ready made) is a fraction of shop prices and that is using the best components, even down to gold component contacts which I guess cheaper shop built ones don't have.
The longest part of the build was selecting components which took a good few weeks as the choice is tremendous, assembly only a couple of hours.
Allthough the heading is for computers I would also add monitors. No good having a sooper dooper computer if the monitor can't handle it. but that is requiring another thread.
