The computer arrived quickly & was reasonably well packed - there was no sign of damage, the exterior of the case being in good condition with no scratches, dents, etc. Included with the PC were an original HP power supply, a USB keyboard, a USB mouse, and some paperwork.At first power on the normal Windows 10 setup process began, culmulating in a fully activated (with digital license) installation of Windows 10 Pro. Checks (CPUz, HWiNFO, etc.) confirmed the hardware to be as specified - Intel i5-6500T CPU, 16GB DDR4 RAM (2 x 8GB modules), 240GB KingFast (???) SSD, etc. CrystalDiskMark indicated typical SATA SSD read/write speeds. Overall, the system felt quite responsive.Unfortunately, my unit arrived without the secondary drive enclosure cooling fan - a problem as I intended to install an M2 NVMe drive (directly beneath the fan location). I contacted the Seller & was told the fan had been removed during the renewal/refurbishing process : reason given - it was deemed 'unnecessary' since the mechanical HDD was replaced by a SSD (??). I queried the implication of it's removal given my intention to install an M2 NVMe SSD - the response was that should I proceed (with the M2 NVMe SSD install) the warranty would be void!!Because of Seller's response re. the missing fan (and warranty!) - which failed to resolve the issue - I returned the computer.
