I'm looking for the smallest case that can accommodate a full ATX motherboard, an ATX power supply, and a 7900 XTX graphics card. Any recommendations?

You might want to take a look at the SilverStone Crown 04; it has a compact design and supports ATX motherboards, although it may be a bit of a tight squeeze for components compared to larger cases.

If you're interested in viewing more options, the Corsair Air 540 could be a decent fit for a mid-tower. Just keep in mind that it's more traditional in design and not the smallest option available.

The smallest viable option would be the SFFTime N-ATX case, but be warned—it’s quite a tricky build. It gives you minimal room, and depending on your specific model of the 7900 XTX and PSU, it might not even fit. If you’re looking for something a bit larger but still compact, check out the Jonsbo D41, which tends to handle most builds well.

BuildMasterJoe: Thanks for the heads-up! My 7900 XTX is the Sapphire Nitro+ model. Any idea if it would fit in that case?

If you’re up for a challenge, the Thermaltake Core X9 or Lian Li Lancool 205M could work. Just know that you might end up battling with cable management, but they are fairly spacious for a mid-tower.

You could also consider the Lian Li Lancool 207; it’s one of the smallest traditional mid-tower cases. Just keep an eye on PSU length, as it has some limits there. For something even tighter, the SSUPD Meshroom S V2 is a strong contender, though it can’t support both ATX PSU and motherboard simultaneously.

TechieGamer42: Got it, I'll check that one out! The limitations sound like they might work with my setup.
