Hi @HeyRosewood1 ,
A search using “Pre-built PC” will bring up many results. Some are not relevant to your question, but many may help guide your decision. Here are a couple to get you started:
Be aware that you generally pay more for pre-built PCs than for the individual components - the mark-up for the convenience of a pre-built can be high. Furthermore, the ability to upgrade a pre-built can be limited too. The sales pitches tend to focus on the CPU & GPU and amount of memory & disk space. Finding specific details about the memory, drives, motherboard, PSU, cooling, fans & other items can be hard if not specified on the manufacturers website. Often it is because they purchase items in very large quantities, and will change them if they can get a better price from their suppliers.
