A few new pc items

I have been thinking and eying a few new pc parts for a long time.  I would really like to build two new frontends that are much more power efficient.  I am hoping I will see a huge difference in my monthly power bill.  Over the weekend I purchased a few parts in my long list of items I want to get eventually.  First was a new power supply.  Since the new floors have been put in, the myth frontend that is in the bedroom seems very noisy.  Normally I would just replace the problem part.  Well in this case, I decided to try a new power supply instead of trying to replace a fan in the special power supply in the case.  I have always wanted picoPSU.  Well I will have one later this week.  This power supply is pretty amazing.  Very efficient and very small.  I hope it does everything I need it to.  From what I can tell, this power supply should work perfectly for any of my energy efficient amd based frontend motherboard and cpu’s.  If it does not, then I will just have to move forward with the last part of my list.  The second item I got is a new M350 Mini-ITX case.  This case is very small.  So small, I got screws so you can mount it to the back of a flat panel display.  The last item ( I have not purchased) yet is an atom based motherboard.  Right now I am looking at a ZOTAC IONITX-C-U Intel Atom N230 Mini ITX ION.  That should be just plenty.  I had looked at the dual core version, but from what I have read, it is not needed when using vdpau.
