I am going to build a budget office pc for my aunt and she wants the cheapest possible in a mini-itx form factor (She said she wants a small computer). So I decided on these two motherboards the MSI B75IA-E33 or the Gigabyte GA-H77N-WiFi, together with a Pentium G2020. The Gigabyte costs $30 (This is counting that I have to buy a WiFi antenna for the MSI) more, I would go with the MSI but does the B75 chipset it's using require a BIOS update for it to work with an Ivy Bridge part?
