- Great HTPC motherboard
- DDR2 for people who want to slowly upgrade and can use RAM already in hand
- SATA slots are placed where a bigger video card can block them
- Very versatile board for people who have AM2 or AM2+ CPUs and DDR2 ram, use this as a HTPC board and used both an older AM2 Athlon x2 4200+ and a Phenom II x4 940 and both worked well ... had older DDR2 ram lying around which was the main reason I went with this instead of a newer chipset

- One really annoying thing about the board is that the SATA ports all are straight up and are where a bigger video card would be seated and would block some of the ports

- 3 Year warranty is also a good plus from Gigabyte

Experience: 4 Months
Very good price for an everything you need HTPC mobo
There is an issue with audio output for HDMI.
The mobo has been fairly good for my HTPC. The overclock capability is decent for a budget build. Managed to get my Athlon 640 to 3.7ghz on it. The only issue i had was the audio problem. Sometimes you will not get sound out of the HDMI. First to get sound from HDMI you must set the audio output default to HDMI. This will make the sound work, however, randomly sometimes after you restart the computer, you will no longer get audio output from HDMI anymore. To fix this, you have to unplug and replug the HDMI for it to detect it again. Although after a while, even this didnt work very often. I had to opt to switch my mobo with my old computer and build another ati 5450 for the other mobo to get HDMI output to the TV... So yeah i wasted another $60 for the 5450.

Simple set-up
Good Value
RAM slots are close to CPU
I'm impressed with this board. It was easy to install and it works very well in my HTPC/Gaming PC. Had a bit of confusion with the HDD activity LED wiring but I'm a n00b and it could've been worse. As with other Gigabyte mobos the RAM slots are close to the CPU slot and I ended up having to take my cooler off and install the RAM first. I've heard that other companies' value boards can be junk so I feel I made a good purchase.

Price as part of an NCIX bundle
Intermittent USB keyboard issues (on boot, in OS it's fine)
Boot from USB is broken in old BIOSes, doesn't work at all in newer BIOSes
PCI RAID controller is detected, but won't boot.
If you're looking for a dead-simple PC, this would probably fit the bill. Personally, I'm ebaying this monstrosity and getting an ASUS, because this board's BIOS is junk junk junk.

Very fast motherboard. Very easy to set up. Nice to be able to use older DDR2 and save a few bucks.
I did need to purchase a more powerful PSU. A PSU that has the 8 pin 12V CPU plug. I know a 4 pin should have worked fine, but I couldnt get it work.

Experience: 3 Weeks

This is good board, lots of options, have enough usb's at the back as well as inside. Nice quality when you see one.

Got the 3.3V, board is blue and white colour.

Experience: 1 Years
Comes with all the functionalities you need for a HTPC build. Very stable.
Wouldn't be first choice for a gaming PC w/o CF. But in that case, you should really look elsewhere.
Grabbed on to build my friend's HTPC for her apartment. Had a few DDR2 modules sitting around and was pleased to find a board that could use new processors with them.

The integrated Radeon 4200 handles most HD contents just fine, but ended up putting a 4670 since she wanted to run a few games on it also.

Versatile (VGA, DVI & HDMI)
Onboard HD Video (Radeon HD4200)
Onboard 7.1 audio
Excellent Price/Feature
None so far!
This is a great motherboard for the foundation of my HTPC. It handles HD playback flawlessly (BluRay, 1080p HD x264 & 1080i TS MPEG-2) without any issues using the HD4200 onboard graphics when paired with an AMD X2 250 using Media Portal on Windows XP. It has been stable and without any issues since I completed the build.

Western Digital Caviar Black 640GB
Kingston HyperX PC2-6400 4GB 2X2GB DDR2-800

grand total was only $400

this motherboard is very cheap and it's good enough.
I can upgrade my cpu and get a video card later on if I want to do some light gaming with this system.
Only downside is that it doesn't have usb 3.0
