To be honest, for your needs I think you'd be OK with any modern chipset board (H77, B75 or Z77). Z77 is mainly for the overclocking (which you couldn't do with an i3 anyway), though it's generally not a lot more in price anyway. Maybe something like the ASRock H77 Pro4. For the CPU, an i3 2100, 2105, 2120, 2125, 2130, 3220, 3225 or 3240. Basically any non-T models (the T models are slow low-power editions). Those are listed in order from slowest to fastest, but you'd have a hard time telling the difference in speed. They're all pretty closely priced too... I'd just grab whatever you find a good price on.
