Cheap but solid.
While the most popular design is mini ITX, this case offers m-ITX / flexATX / m-DTX support and has THREE PCI slots. It means that is designed to take "ITX expanded boards" with TWO PCIE slots instead of just one. It makes cost of build cheaper due to lower priced flexATX / m-DTX boards. Jonsbo C2 is made from thick and stiff aluminium sheets and despite of simple construction is able to offer good stiffness and it looks very impressive. Overall it is a solid offer for casual use and for light gaming.
Unfortunately, there is few issues with space inside related to the full size ATX PSU, especially fully wired. So the best option is to use semi/ fully modular PSU or even better to use SFX PSU but semi or fully modular as well. Air circulation is sufficient for, as mentioned above, only average use. Heavy loaded systems will overheat and may throttle due to limited amount and size of vent slots and holes. Additional case fan will be good idea to have fitted. Anyway, worth to buy.
