The InWin A5 is a pretty unique proposition. With its $105 price tag, it has quite the mass market appeal to start with, considering it is hovering around that magical $100 mark, but doesn't really offer the same set of features, build or function as essentially all other enclosures in that price segment.
Officially a Mid-Tower chassis, the InWin A5 is actually quite compact. As such it may be surprising to some that it can hold an E-ATX board without any tangible compromise. Even more surprising if you look at the interior and initially see a very simple layout without too much engineering. With that in mind, potential buyers who don't dig further may write the chassis off in favor of other products that provide 4-5 ARGB fans, ARGB controllers and better liquid cooling support. And to those that do: that is probably the right choice as the InWin A5 aims at a more focused use case, managing to do so well.
If you are aiming to use an E-ATX board and want a compact chassis, the InWin A5 may be a great choice without breaking the bank, so that you may focus on spending that budget on better hardware. The biggest limitation is probably the fact that the chassis can only hold a 240 mm radiator, even if that is enough for most users. Luckily you may install two fans in the floor, providing some additional cooling to the GPU and offsetting the fact that the front of the InWin A5 is completely solid.
Even with the well laid out interior, the InWin A5 does feel too simple at times. The HDD mounting position in the floor should really be utilizing a removable plate and the lack of hooks to zip tie is quite odd as well. Then there are a few visual annoyances like the blue USB ports or heavy glass tint, but even with those, the InWin A5 looks and feels sturdier than most other cases in its price segment.
Essentially, while it may cost the same as most mainstream offerings while offering fewer functional features, the InWin A5 makes up for that in build quality and compactness, with surprisingly little compromise when it comes to filling the case, even with physically large or long hardware. If you are looking for a compact E-ATX case that doesn't cost an arm and a leg, the InWin A5 can certainly be recommended.
