I'm considering buying a prebuilt PC, but I'm concerned about upgradeability. I know some brands, like Alienware, are known for using proprietary parts that limit upgrades. What are some signs that a prebuilt PC is upgradeable? Also, are there better brands or options available, preferably ones from Best Buy?

It's best to avoid HP, Dell, Alienware, and Lenovo for upgrades. Systems from iBUYPOWER and CyberPower usually have standard components. However, keep in mind that many prebuilts are designed just for basic use; upgrading can be more hassle than just building one from scratch.
When looking for a prebuilt PC, steer clear of brands like Dell and HP. Check if the motherboard is standard. If it is, the other components usually are too. You might want to ask for recommendations in specific forums too!
Make sure to investigate if the back of the case has a removable I/O shield and whether the power supply fits standard sizes. Typically, prebuilt PCs can be upgraded, but it might take a bit of extra work, and you may need to swap out multiple parts at once to really boost performance.
Brands like CyberPowerPC or iBuyPower generally use standard components. The big offenders are usually Dell and Alienware with their proprietary designs. HP can be tricky with firmware locks on their motherboards that complicate CPU upgrades.
Honestly, the prebuilt PCs at Best Buy don't usually cut it. If you're looking for a solid build, check out places like ZTT, SkyTech, or ABS on Newegg instead.

Yeah, Lenovo falls in the same category as HP with their proprietary parts.
