I'm building a PC for my family that will mainly be used for some office applications, youtube, web browsing, etc. Nothing too demanding actually and I really doubt any games will be played on it. The idea is to create a decently powered PC which will withstand another 5 years like the current Dell Pentium 4 PC we have, however, I want it to run on as little power as possible. I plan on undervolting the processor to the lowest minimum stable state which I believe will make quite a difference since the one I have chosen tends to have really high stock voltages.
Here is what I have built so far but if you have recommendations to make it even cheaper without losing integrated graphics and basic features, please let me know.
