I remember reading that the i3 was almost as fast as an i5, but 
significantly cheaper. But anyway, for my own use I was looking at the 
i3 for an always-on media center. My Dual Core 1.6 GHz has enough power 
for that, even if decoding 1080p in software (VDPAU hasn't been very 
reliable for me) since the software is able to use both cores. I'm 
guessing the i3 3220T (the low TDP version) would be more than enough.

Does anyone know if some of the newer Atoms are powerful enough to 
decode 1080p by themselves?

What I don't like about most boards out there (even the better brands 
like Asus and Gigabyte) is the Realtek Gigabit adapter. I don't like 
Realtek ethernet in general and I have had problems with some of their 
Gigabit chipsets. Because of this I'd prefer an Intel board. For me I 
would go for the DH77DF (mini ITX).

Sure. If that is not enough it's always possible to add a dedicated 
card, even on the mini ITX boards (but size may be a problem there).

Right now I'm quite ok with 2 GiB. I'm guessing... 8 should do ;)

The Antec ISK 310-150 (150W power supply) look great and has lots of HDD
bays for such a small case.

My total HDD storage capacity is currently 320 GiB. Putting a 60 GiB SSD 
in my laptop would give it a boost and I could use the laptop's 160 GiB 
drive for the media center.

Useless for me.

Unfortunately I have to agree with you.

I trust (pun not intended) FLOSS developers more.

Unfortunately my system described above will set me back more than 400 
EUR (on ebay.de, in Romania it's even worse), which is why I'm looking 
at even lower powered alternatives, like Atoms.

The Raspberry Pi almost does it (by using hardware decoding), but it has 
other issues :(
