I don't do gaming, haven't needed tech support, and don't use sleep mode, so I don't know about those things. But, I surf the Internet, (Internet Relay Chat, YouTube videos, email, news & weather, etc.) and this small desktop is perfect for those things. I'm very impressed with the level of restoration. (Couldn't have done better myself. <grin>) The ONLY issue I had is one most folks would not. The new SSD came set up MBR instead of GPT, forcing Windows to run in Legacy (BIOS) mode instead of the newer, better, UEFI, and preventing me from adding a Linux OS to dual boot, without quite a lot of work. I avoided that by simply opening the case up and installing another SSD for my Linux OS. I can't transfer files between the two operating systems this way, but that isn't very important to me. Works fine this way, and most folks only run one OS anyway. I am very pleased with this purchase. I feel I got a real bargain. Nice desktop computer. Especially for the price.
