deiced between 2 HTPC barebone

Halo

after a long time I have decided to buy a bare bone system.
I spent a long time on line but find it very hard reach a decision:
I want to buy a system that can easily run 1080 and hold even the heaviest xbmc skin (eg AEON) and be very silent!!. I think its a group #6
the media will be streamed from a home server I will set up.
Initially I thought about going with a e450 system, either Foxconn nt-A3700 or the Zbox AD04, but I am concern about the heat and their capacity to smoothly run the skin.
now I lean towards one of this two systems Zbox ID82 (http://www.newegg.com/Product/Product.as...856173045) or the EcoSmart E-i5 AMD A6-5400K (http://www.ecosmartpc.com/ei5amdtrinity.html).
I will supplement the system with 2X2G ram and 64GB SSD.

any helpful tips will be very welcomed.
thanks
