Is it a good idea to buy PC parts at Micro Center and have them build it?

Yes, that can be a convenient way to do it. An employee can help you choose parts, and Micro Center has offered paid assembly. Check with your local store for the current service options, price and turnaround time.

Tell them whether your budget includes the build fee, and what you want to use the PC for. Ask for an itemized parts list before committing so you can check the prices and specs.

I would compare a parts list rather than assume one store has the best price on everything. Check Micro Center's processor and motherboard bundles, then look at other retailers for the graphics card and remaining parts. Make sure the bundle has what you need before counting it as a saving.

You can use the store's online configuration tool and a parts comparison site to work out the total. Prices and stock can change, so check them close to when you plan to buy.

Also compare a prebuilt PC from the store. If the price is close to a custom parts list plus assembly, it could be the simpler choice. Look beyond the processor and graphics card though. Check the power supply details, cooling, ports and other components, and ask about anything the listing leaves unclear.

Assembly is the cost to watch at this budget. Paying for convenience is perfectly reasonable, but get the actual quote first. If the fee takes too much out of the parts budget, building it yourself could leave more money for the hardware.
