Do the parts fit together?

No problems found. We only check what the stores' listings say. "Check fit" means they don't tell us, so look before you buy.

Check fit The case's listing doesn't say which motherboards it takes. Make sure the case takes a Micro ATX motherboard.
Check fit We don't have the cooler's height or the case's CPU cooler clearance. Compare them before you buy.
OK The processor and the motherboard are both AM4.
OK The memory and the motherboard are both DDR4.

Windows 11 Home license: $139.00 (Microsoft's price; leave it out if you already have Windows)

Prebuilt or build it yourself?

What the prebuilt includes: The $720 prebuilt comes assembled and tested, with Windows installed, one warranty for the whole PC and one place to call for support. Parts come with a warranty each, and you install Windows yourself.

Where it may cut corners:

It doesn't name its motherboard; a budget board can limit upgrades.
It doesn't list its power supply; an unbranded one is a common corner cut.
It doesn't list its CPU cooler; a basic stock cooler runs hotter and louder.

Time and skill: A first build takes about 3 to 5 hours with care: seating the CPU and memory, mounting the cooler, routing cables and installing Windows and drivers. No special tools beyond a screwdriver.

Our take: We could not price every part today, so compare again tomorrow before deciding.
