My build is much more modest. A mid range gigabyte motherboard, i3, 4 GB of memory. I did invest in a 128 GB SSD for the OS, with /home mounted on a 1 TB 10k spinner. I love that SSD/HDD split, makes a very noticeable difference, even with modest components.
I’ve thought about doing the same hard drive setup. Are you running W10 on it? If so, what is your boot time like?
