The bad part about that Gigabyte MB is that if you are using a dual slot vid card it covers 2 of the 4 SATA connections on the board so if you have more than one HD and Optical, even with a right angle SATA cable, it can still cause issues. The biostar board will only have 1 of the 4 covered.
Personally I would spend an extra $5 and go for this MB: ASRock H61M-VS
It has much better layout with the sata connections than the previous 2 boards.
True, the Celerons are typically not associated with higher end functions or gaming, but with these new Celeron processors based on the Sandy Bridge architecture, they are able to accomplish much higher performance.
I'm at work, so it might take me a little bit, but I'll see if I can dig up where I saw the reviews for the G860, but it is very similar to the i3-2100 only without the hyperthreading.
