I'm planning a gaming PC with a budget of roughly $2,200 and would appreciate a compatibility check before ordering. The build includes a Ryzen 7 7800X3D, an XFX Radeon RX 9070 XT, 32GB of Patriot Viper DDR5-6000 CL30 memory, an MSI B850 Gaming Plus WiFi motherboard, a Kingston KC3000 2TB M.2 SSD that I already own, a Lian Li Vector 100R case, an MSI MAG A750GL PCIe 5 750W 80+ Gold modular power supply, and an Arctic Liquid Freezer III Pro 360 AIO cooler. My main concern is whether the 360mm radiator will fit properly in the case, particularly around the RAM and motherboard. I've seen builds using this case and cooler together, but I'd like confirmation that installation should work without replacing fans or making other changes. Suggestions for improving the parts selection are welcome too.

The 360mm Arctic AIO should fit when mounted at the top of the case. It shouldn’t cause problems with the memory or motherboard in this configuration, so you likely won’t need to swap fans or make special modifications. Just check the case manual for the recommended radiator and fan orientation before assembling.
The parts look broadly compatible. The main thing I’d reconsider is the power supply’s value—750W is a reasonable capacity for this system, but that particular model may be expensive depending on local prices. Since you’re buying in Poland, compare it with other reputable 750W or 850W Gold units available there. If the price difference is small, 850W gives you a little more headroom.
I’m buying in Poland, where PC parts are unfortunately quite expensive. I’m ready to upgrade now rather than keep waiting for prices to drop, but I’ll still compare equivalent power supplies if there are better-priced options.

Thanks! I’m new to using an AIO, so I mainly wanted to confirm that the installation should be straightforward and that there wouldn’t be unexpected clearance issues.
