I rebuilt my HTPC lately using the DH77EB. It's a wonderful board and I recommend it to anyone!
Here's the setup
Intel Pentium G2120 CPU + Noctua NH-U12P passive
Intel DH77EB mATX MB
Kingston 2x4GB 1600Mhz CL9 1.35v
Gigabyte HD5670 + Accelero S1 rev2 passive
Samsung 830 64gb OS drive
WD1001FALS 1TB storage drive
Lian Li PC-A05NB + 120mm Slip Stream PWM @300rpm + 1450rpm Gentle Typhoon @600rpm
A couple of pics
Here's my power consumption readings I posted at my build log @[H]
Temperature wise excellent. CPU doesn't even warm up, in worst case scenario á la IBT I see it maxing 46*C Now that the CPU ain't running warm and neither do I have a REALLY hot NB (80-100+*C) just below the GPU the GPU is running cooler as well.
The heatsink with the Athlon was quite warm to the touch and I did have a bad contact on the old build but still now the heatsink isn't warm at all.
Power wise excellent. Loaned a Christ Electronic CLM200 and sitting on desktop 43-45w, watching TV Win7 WMC 50w, MPC-HC (madVR+LAV) 50-60w depending on material, IBT ~60-61w, Furmark ~74w
IBT+Furmark was difficult to measure but around 90-95w, but under 100w anyway.
Previous setup was with Athlon II X2 240 + Gigabyte GA-MA78GM-S2H + 4GB DDR2 + the rest of the parts I currently have.
I'll be getting the Seasonic X-400 V2 fanless psu on friday. Will update my post with new power readings then. After I've sold my HD5750 (don't need it anymore) and the current S12II-330w PSU and my XFX-550w (getting 660XP2) I'll probably look into buying a HD7750 or a GTX650, one of those models that don't require external PCI-e power.
Deep idle with the HTPC it pulls 41.2-41.5w and since the HD5670 is pulling something like 14-16w... This is of course with LAN NIC enabled and the WD1001FALS spinning but display turned off..
