So here's the 2008 Mac Pro with 2 x Quad Core (that's Octocore) 2.8GHz Xeon processors, 10Gbs of RAM, 60GB SSD for MacOS, 320GB and 1TB SATA storage drives for source/scratch disks, and while I don't have a long enough SATA cable, I'll be putting my Blu-Ray drive into the second optical bay, it's currently external via USB. The Mac Pro currently has a DVD-RAM burner already. Currently has 10.11.6 El Capitan but can be patched to allow for macOS Sierra 10.12.x. Graphics are currently an ATI Radeon HD 2600 XT 256MB, but with Nvidia drivers now covering the entire GeForce GTX line, I'll probably get something better eventually.
Both my MacBook Pro and my Mac Pro are backing up to a 1TB Time Capsule, which is also my internet router, both wired (for the Mac Pro) and wireless (for my MacBook Pro and iDevices). I have a wired JIS JP keyboard, wireless US keyboard, original magic mouse, and second generation remote. Also iPhone 6S and iPhone 4 (currently on loan to a friend who broke her phone).
Non-Apple things: Bose speakers (for enjoyment), Sony headphones (for editing), LG Flatron IPS 23" monitor (probably will be replaced or doubled, but not any time soon), Epson EB-S62 projector.
I live in a small studio, so images include stuff that is important to me like my Japanese diploma, some posters, figures, awards (Katsucon and Anime Evolution are visible), animoo source not ripped to Mac Pro harddrives, clothing, etc.
