This was the only one I could find on Newegg. Biostar isn't the best brand for motherboards, and it might be worth your while to find a motherboard that has fewer USB ports on the back panel and use a breakout to get the additional ports, in exchange for better build quality.
I checked the CPU support and the Q8400 is listed, but without knowing the model number for the RAM I couldn't check for certain if your RAM is qualified on the board.
If you're fine at running your RAM at 800, or using a USB breakout, it would open up your options substantially, and you'd probably find something a little better.
