My Family has been using an xps 400 for the past 10 years. When my friends and I got into custom building I realized computers did not have to be expensive anymore. The xp had been acting up and my mom was also ready for an upgrade. Fearing my parents would go buy a store bought computer, I convinced them to let me build one. Ironically enough the next day after buying the parts the xp shut down and never turned back on, as if it had retired itself.
For this build I had two criteria: speed (I never wanted my parents to say those awful words again "our computer is slow". , and to be under 600$. Remember this not a gaming build it is only for mom and dad stuff although I can play games on it at lower settings. This computer is great for minecraft though, I get 65 fps with settings maxed. I am also using at 1920X1080p
I'm am not going to go over all the parts because some of them are reviewed enough.
CPU: Great cpu, especially for non gaming. I know I could have gotten away with an i3 but I wanted the extra leg room and the newest components.
Motherboard: again great for non gaming, if you are gaming with 4th gen core then get the z87 chip set instead. This is great for home use.
RAM: Good ram, I think it was the cheapest when i got it so i just selected it. I wanted to get 1600 so it suited my needs.
SSD: I can not say enough good things about Solid States, Windows 7 starts up and is ready in 15 seconds. The 64GB did work but I recommend getting a 128GB because after all the updates, programs, and drivers I have 19GB of free space. If you have a tight budget though you can fit everything on a 64GB you just need to be frugal.
Case: good case for the money, had everything I needed and keeps the inside cool. Unfortunately I could not get the CPU power plug to go any where behind the motherboard but its not like mum will open up the hood and judge my management.
In all it cost 550$ at the time. I am Thinking of building my own gaming Build also so this was a good experience.
