Here is a small Intel Pentium G3220 3.0 GHz HTPC computer build I created to stream video. I also use this small form fact PC to educate our children as they are home schooled. It run Windows 7 Home 64-bit because it is more compatible with old educational software.
This is a pretty fast budget dual-core CPU that is highly overclock-able even with the stock cooler.
As always G.Skill make awesome memory. It is stable and work very well.
A great Micro-ATX tower for the price. I has a great look and looks quite stylish. The only issue I have is there is very little room for cable management. It also feels a little then but well seems quite sturdy. I would still recommend this as a good case to do a budget build.
