A lot of choosing a case is aesthetics. Personally I think that case is pretty nasty looking, but it's not me who has to live with it.
Cases do matter, and there are a lot of things to consider.
- Build quality - You are unlikely to be able to tell this from a picture but reviews will give you an idea. Lower quality materials or extensive use of plastics can result in a case that is creaky or awkward to work with.
- Airflow - Is it supplied with quality fans, how is the airflow set up, is it well vented. Is airflow even important to you?
- Clearances - Cases will have a limit to the length of graphics card, height of CPU cooler and sometimes the length of PSU they support. If you plan on using larger versions of any of these components, it's worth checking.
- Interface support - Most motherboards now have a USB3.0 internal header, this will support front USB3.0. Depending on your preferences, a large number of front USB might be preferable.
- Size - Cases vary a lot in size, if you have limited space this is worth checking out.
- Motherboard support - Most cases support all motherboards below their maximum size, so a case supporting standard ATX boards will usually support mATX and ITX (as they use the same standoffs)
All of that is significant, but in reality a lot of mainstream mid-tower cases will answer a lot of these questions for you by providing support for pretty much everything. I don't know anything about the case you linked, but in general I'm familiar with Raidmax budget cases. A range that seems superficially similar but is usually well reviewed is the Coolermaster HAF range (912/922)
