My old motherboard recently failed, so I bought a B550 Phantom Gaming 4 as a replacement, but it doesn't fit inside my current case. I'm looking for an inexpensive, functional case that supports a full-size ATX motherboard and has decent airflow with preinstalled fans if possible. I don't care about appearance, glass panels, or RGB, and I'd prefer to keep the power button, USB ports, and headphone jacks on the top of the case. I'm located in Germany and would rather not spend much. I originally hoped to find a case that included a power supply and cooling, but I now understand that cases with built-in PSUs are uncommon, especially for ATX systems. What models or features should I look for?

Look for an ATX mid-tower with a mesh front panel and at least two or three preinstalled fans. That will give you the airflow you need without paying extra for appearance features. Cases with a power supply included are uncommon, and bundled PSUs are often low quality, so it’s usually safer to buy a separate PSU from a reputable brand. You can compare prices from German retailers using a PC parts compatibility site, and check that the case supports ATX motherboards and has enough room for your graphics card and CPU cooler.
Since you’re in Germany and have a tight budget, focus on inexpensive airflow-oriented ATX cases from established brands rather than searching for a case-and-PSU bundle. Confirm the front panel is mesh, check how many fans are included, and look at the fan sizes and mounting positions. Top-mounted power and I/O controls are common, but verify the product photos and specifications before ordering. Also make sure the case includes enough clearance for your components and has a removable dust filter if possible.
Top-mounted power, USB ports, and audio connections would be convenient because my previous case had them, but appearance and RGB don’t matter to me.

Yes, I meant preinstalled case fans rather than a built-in CPU cooler. Good airflow is the main thing I’m after.
