I also did this (around ~2008), a friend of mine and I built near identical Atom boxes with first gen (Diamondville) 64bit atoms on Intel motherboards running 865 chipsets IIRC. The GPU/Chipset was louder than the CPU because the CPU was completely passive. I did emerge Xorg on that... it took I think a day and a half(ish) even optimizing the heck out of compile options to use everything march=native... it was slow as heck. But it lasted me for years as a little project box until I replaced it with an 4th gen i5. You really do start to ask yourself if you need a package if compiling it will take a day or two. Hence OpenOffice never got installed.
