Streacom FC8 EVO - AMD A8-5500 build

Hi,

I'm considering the build below for my first HTPC.
Main usage would be XBMC playing 1080p movies and also streaming Silverlight (Viaplay, Netflix etc).



(Prices are in SEK (Swedish Krona) including VAT and total price will probably end up at about 5000 SEK buying from two different webstores. 5000 SEK is about $750 / £470.)

Also planning to possibly add a bluray-player in the future.

I've been reading some of the threads here about the different FM2 builds and the Trinity APU's maybe using a bit much power.
# Will the Streacom 150w nanoPSU be ok for the A8-5500 with a SSD and ODD ?
# Would there be to much heat for the Streacom FC8 EVO case ? Will I have to undervolt/underclock (in BIOS/UEFI or using PSCheck) to keep the heat down ?

Any other comments or suggestions would also be highly appreciated.

Thanks
