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 Make sure the motherboard takes DDR5; the motherboard's listing doesn't say which it takes.
Check fit The case's listing doesn't say which motherboards it takes. Make sure the case takes a Mini-ITX motherboard.
Check fit Make sure the case has room for a radiator (the case's listing doesn't say).
OK The processor and the motherboard are both LGA1700.

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 $4,198 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.

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.
