Mac Pro 2010 5,1 Running OS X Catalina 10.15.3 and all current updates. 28GB System Memory (RAM) 2TB Hard Disk Drive 1TB Hard Disk Drive 1TB Hard Disk Drive 500GB Solid-State Drive (SSD) Bluetooth AirPort Extreme Firewire 400/800 x 4 USB x 5 Gigabit Ethernet x 2 DVI Video Output x 2 Tousling TOSLINK (Fibre-optic) x 2 Digital/Analog Audio in/out Superdrive DVD/RW There is still the ability to run more drives, the second optical bay is empty, and there are 3 PCIe slots available. You could make the machine even faster by adding a cheap NVME PCIe bus slot card drive. You could add more, or faster video cards, audio cards, etc. I also added USB 3.1 to my other 5,1 Likely if you are reading this; you know how expandable these machine are, and how you further you can customize them, versus anything else remotely affordable. Delivery could be possible. Cheese-grater Cheesegrater 5.1 MacPro Tower Workstation cMP
