We have the same idea Bro .... 780G is a really good chipset for HTPC, but I would recommend the Gigabyte over Emaxx because of DTS Connect support available on the Gigabyte MoBo ...there's also the new 790G chipset coming up, the only difference is the "sideport" - this functions as some sort of discrete memory or cash for the video processor and said to improve performance on 3d gaming at almost the same price level of the 780G ... my only worry about the Gigabyte 790G is that it supports Dolby environment, but the DTS logo is no longer included, hence I think the 780G would still be better if your primary usage is HTPC and not gaming.
To complement this, and if you're really thinking of budget HTPC, there's the Antec NSK1360 mini-casing with an 80%+ efficiency power supply built-in ...it sells at around 4k+ in Gilmore QC ... or if you have more budget, there's the Antec Fusion 430 HTPC casing (sold in black & silver) at around 9K+ - this has a built-in power supply, front panel display and remote, and this will blend in nicely with any of your other AV components...i'm not recommending the cheap casing with low-end power supply units because the usual usage for HTPC's are usually higher, and the fans included on cheap power supply units are usually noisy (no good for HTPC).
