Built for an economy machine running Linux. Installed Edubuntu. Works like a dream. Linux has come a long ways from text entry to graphics interface competitive with latest Windows or Mac operating systems. OS would be transparent to most users. Used the parts listed below plus an 80G hard drive (bulk purchase from ebay). So entire system is about $160. Edubuntu would run but not install until hard drive was formatted using a formatting utility. Wireless connected immediately. Case is nice and roomy though the motherboard has only two card slots (PCI and PCIe). Motherboard and CPU combo was a big help since didn't have to risk damaging socket (been there, done that). Motherboard and case wires mated well though had to do a little research on power and reset connector locations. Wouldn't change a thing and plan to make a dozen with the rest of the hard drives. PCPartPicker was a huge help with compatibility.
