Meet the Biostar B550 GTQ motherboard. It’s a rather entry-level mATX product from the Racing series, which also includes an ATX form factor version. The design is rather attractive, with a consistent black-and-grey theme. This is a 24.4 x 24.4 cm, mATX-factor product equipped with a B550 chipset, and it offers such features as 6+4-phase power design (Dr MOS) and 1x Gigabit ethernet (the ATX version has 2.5 Gbps). Priced at about 130 USD, it’s definitely a cheap one, in the range of B450 motherboards.
