It’s A Bit Large But Definitely Cool
Mini-ITX cases do not often allow you to install six 120mm fans, or four 140mm fans, or even up to a 360mm radiator, not unless it happens to be the Jonsplus i110 Pro apparently. Measuring 322mm high, 435mm deep and 194mm wide (12.7×17.1×7.6″) the i110 Pro is almost big enough for a full ATX board, but the layout does preclude that. It also offers you the choice to mount your GPU vertically or horizontally as you prefer, unless a large CPU heatsink makes that decision for you.
The case is made of aluminium and steel with tinted glass panels on both sides of the case, which does make it hard to hide your cables. With the internal layout you may be able to squeeze in a compact ATX PSU, but you will have an easier time with an SFX PSU instead. The cooling of the case is impressive, as you might expect from the number of fans that can be installed, something you will need to consider as Jonsplus doesn’t seem to have included any with the i110 Pro.
