I mainly play games on a PS5 and Switch 2, so I'm not looking for a powerful gaming PC. I'd just like something inexpensive for games that aren't available on consoles, such as indie horror titles, visual novels, Minecraft, and similar lightweight games.
I still have an HP desktop from around 2011, but it stopped working sometime around 2014–2016. I don't remember whether it simply became slow or whether it developed a hardware problem. The last time it worked, it handled Minecraft and a couple of Slender games without trouble. The front only says AMD and NVIDIA GeForce, so I don't know the exact processor, graphics card, or amount of memory.
The computer was used on many questionable websites, so I'd want to erase everything and start fresh. Would a complete drive wipe and clean operating-system installation remove malware? It probably has Windows 7 installed, so I'm also wondering whether newer Windows would work on it.
It originally needed a USB Wi-Fi adapter, so I'd need to replace that or install another wireless solution. Would a decent Wi-Fi connection be sufficient for multiplayer games? I'm also curious whether upgrading one or two inexpensive components could make the system worthwhile. Finally, could the old HP case easily be replaced with a smaller or newer case, or are older prebuilts usually difficult to move into another case?
I'm open to buying a newer mini PC or entry-level gaming computer if reviving this one would be more trouble than it's worth, but I don't want to spend $700–$800 unless there's a good reason.

The most sensible low-cost test is to clean the dust out, try a known-good power cable, inspect the power supply, and see whether it reaches the startup screen. If it works, check the model number and specifications, replace the hard drive with an SSD if needed, and install a clean supported system. Don’t spend much on upgrades until you know what hardware is inside. A $380 mini PC could be a better fit, but verify that it has a reasonably modern processor, at least 16 GB of memory if possible, and enough graphics performance for the games you want.
Wi-Fi itself generally won’t determine whether a game runs well. It affects connection quality, latency, and downloads, while the CPU and GPU handle the actual game. A modern USB Wi-Fi adapter should be fine as long as the old operating system has compatible drivers. For multiplayer, Ethernet is preferable when possible, but decent wireless is usually enough for lightweight games.
Be careful assuming the case can be swapped. Many HP desktops from that era used proprietary motherboard layouts, front-panel connectors, power supplies, or mounting points, so moving the parts into a standard case can become a frustrating project. The graphics card and storage might be reusable, but the case itself is usually not a worthwhile upgrade. If you want a smaller system, buying a newer mini PC is likely easier than rebuilding this one.
A factory reset is not the best approach for an old machine. If you want to be confident it is clean, erase the drive completely and install a supported operating system from official installation media. Windows 7 should not be used online anymore, and the computer may not officially support a modern Windows version. A lightweight Linux distribution could work well for basic games, though compatibility varies. Also, an old hard drive may be failing after years of storage, so replacing it with a cheap SATA SSD would be the most noticeable upgrade if the system is worth keeping.
It may be possible, but it probably isn’t practical without knowing the exact model and specifications. A 2011 system could still run some very lightweight games, but the old processor, graphics card, storage, and limited memory may make upgrades poor value. First check whether it powers on at all, then identify the exact HP model and hardware before buying anything. A newer used office PC or mini PC would likely be faster, quieter, and less troublesome.
That makes sense. I didn’t realize the exact model mattered so much, so I’ll check the label and internal hardware before deciding.
