I bought a $500 gaming PC about two months ago. It currently has an RX 560 and a Ryzen 5 3500X, but I'm considering upgrading to a three-fan Gigabyte RTX 3070 Ti Gaming OC listed for $275 through a local marketplace. I'm worried the card may be too long for my case. The case measures approximately 11.22 inches wide, 14.57 inches tall, and 18.7 inches deep. Is that enough information to determine whether the graphics card will fit, and what else should I check before buying?

Those outside case dimensions aren’t enough to confirm compatibility. You need the exact case model, then check the manufacturer’s specifications for maximum GPU length and compare that with the 3070 Ti’s listed length. Also check whether a front radiator, drive cage, or other components reduce the available space. A photo can help identify the case, but the model number is much more reliable.
Before buying, verify more than just the physical fit. A 3070 Ti typically needs a strong power supply with the correct PCIe power connectors, and your Ryzen 5 3500X may limit performance in some games. Ask the seller for the exact card model and measurements, inspect it in person, and make sure the price isn’t suspiciously low.
