I'm taking a look inside a HP Z4G4 workstation is recently bought renewed from Amazon. I'm taking a look at the cooling, hard drive, USB board, RAM and a few other components. Overall the workstation seems put together well and there is plenty of space for extensions and upgrades. It's not the newest kid on the block anymore, but for the price of around $500, it's very good value and still delivers great computing power for most tasks and multitasks, including image and video processing, and even gaming.
