Why would you NOT build you own machine? The Benefits are far to great, Better parts , cost savings, control in picking the components, etc. The only down side for those of you who use it is the cost of Windows becomes a tad more obvious.I have never once got a pre-built, the closest thing i have to one of those is a laptop because they are not cheaper to build. KM is right OEM's generally don't have a record of using higher quality parts and when they do you pay for at least a 150% markup for them. In the past 20ish years that I've been building computers they have become much easier to build.Today's computers can be built by anyone who can use a screwdriver,line up a few dots and plug in a few cables. The issues that complicated the builds of old; IRQ conflicts, needing to set jumpers for everything and manually telling the bios about your hardware no longer exist. Just about all hardware just plugs easily and only one way. the only thing post build needed to be done is install the OS that too is much easier today.
