I'm building my first PC after only using prebuilts, and I'd like to use a smaller case instead of a typical full-size ATX tower. I know a compact build may be more challenging for a beginner, but I'm willing to plan carefully. My current parts list includes a graphics card from my existing computer, while the other components would be new. My total budget is around $2,000 CAD or less. What compact cases would suit this build, and which case fans would you recommend if they aren't included? Are any components likely to have clearance problems, especially the RAM and CPU cooler? I'd also appreciate feedback on anything else that seems incompatible or poorly balanced, along with general advice for assembling a small-form-factor PC.

The build order matters more in a small case because access becomes limited once parts are installed. Connect the CPU power cable and front-panel headers before mounting the cooler if the case makes those ports difficult to reach afterward. It’s also worth test-fitting the motherboard, cooler, and memory outside the case first. Install the cooler’s fan at the correct height, then measure the total cooler height and compare it with the case’s published maximum rather than relying only on the cooler’s basic dimensions.
Since the graphics card is being reused, measure its exact length, height, and slot thickness first; those are often the parts that eliminate otherwise suitable compact cases. Use the case manufacturer’s clearance figures rather than just checking whether the card technically fits. Leave room for power cables and airflow, especially if the card is a thick model. A couple of quality 120 mm or 140 mm intake and exhaust fans can help, but don’t overcrowd a small case—one front or bottom intake and one rear or top exhaust is a sensible starting point.
For a compact build, check the case specifications against every major component before buying: motherboard form factor, graphics-card length and thickness, CPU-cooler height, power-supply format, radiator support, and fan positions. The listed cooler height usually assumes the fan is installed in its standard position. If the RAM modules are tall, you may need to raise the front fan, which increases the cooler’s total height and can exceed the case limit. A case with generous CPU-cooler and memory clearance will make a first build much less frustrating.
