I've been planning a gaming PC build with a total budget of about $900, but I'm unsure whether to choose a compact Mini-ITX case or a regular ATX setup. Space is somewhat limited, so a smaller build sounds appealing, but I've heard that ATX systems usually have better airflow and are easier to upgrade, troubleshoot, and manage cables in the future.
The main games would be Valorant, Apex Legends, and older AAA titles at 1080p and 60 FPS. I'm mostly looking for stable performance without stuttering or strange lag spikes rather than an extreme high-end system.
For anyone who has built in Mini-ITX cases, did the higher component prices, tighter thermals, or difficult cable management make you regret it? Would Micro-ATX be a better compromise? I'm also wondering whether Mini-ITX actually saves money at this budget, or whether the smaller motherboard, power supply, and case end up costing more than equivalent ATX parts. A used PC is also an option if it offers better value.

Before choosing Mini-ITX, figure out how much space you actually need to save. Many compact cases mainly reduce the footprint or height rather than making the whole setup dramatically smaller. If you already have room for a desk, a compact Micro-ATX case may provide nearly the same practical benefit with easier assembly and cooling.
Micro-ATX is probably the sweet spot here. You get a smaller footprint than a typical ATX tower without paying as much of a size premium, and there’s still enough room for a normal graphics card, decent cooling, and future upgrades.
Mini-ITX usually costs more than ATX because the motherboards, power supplies, and cases tend to carry a premium. With a $900 budget, Micro-ATX is generally a much better fit, and it may be worth comparing against a good used gaming PC as well.
That’s what I was worried about with Mini-ITX pricing. With the budget increased to $900, Micro-ATX or regular ATX seems more practical, though I’ll still check used systems for comparison.
A small Micro-ATX case can still be surprisingly compact. Something in the size range of a Jonsbo C6 can fit a two-fan graphics card and should handle 1080p gaming comfortably. Going slightly larger gives you room for a full-size GPU and a better tower cooler, so the best case depends on how much upgrade flexibility you want.
The point about saving mostly vertical space is fair. I do have room for a full-size case, so I’m leaning toward a standard ATX or Micro-ATX build instead of choosing Mini-ITX just for the compact look.
