I have an HP Z2 G4 workstation turned gaming PC. It has a 6 core I5 processor, 16GB DDR4 RAM, a 256GB Samsung NVMe SSD, WiFi, Bluetooth, Radeon RX560 graphics card, and a fresh installation of Windows 11 Pro on a local user account. This system works great for Minecraft, Roblox, and older titles as is. Newer titles may not run on higher settings unless the graphics card is replaced with a more powerful one. The power supply has 6+6+2 power available for a beefier card, which makes upgrading easy. There are also 2 SATA drive bays with trays and an additional NVMe slot available. This budget system can become a monster with a couple easy additions. It would be great to grow over time as you or your childrens needs grow.
