On Wednesday evening my used (new to me) HP Z2 G4 Mid-Tower Workstation arrived. It is:
Intel Core i9-9900 i5-9500 until USPS delivers the i9
32GB (2x16GB) DDR4 2666MHz Unbuffered Memory (as fast as HP will allow)
2TB M.2 NVMe Solid State Drive and 500 GB M.2 NVMe Solid State Drive
4GB AMD Radeon RX 560X GPU (would like to replace this, but will take big $$$)
Integrated Intel I219-LM 10/100/1000 Gigabit Ethernet (will likely never be used)
Integrated Conexant CX20632 5.1 High-Definition Audio
HP 500W 90% Efficient Power Supply (very nice PSU for a major PC manufacturer)
Debian Linux 13.5 with xfce/Microsoft Windows 11 Pro (came preinstalled, so I'm dual-booting)
It's much nicer than the HP Pavilion I had been using. The i5 I'm, temporarily, using has six cores instead of four like the Pavilion CPU had. This allows to me to give my Windows VMs four cores instead of two, and they're much more responsive. The i9 that is supposed to arrive tomorrow has eight cores and sixteen threads.
Good times!!
