Your requirements would be "minimal" but I'd recommend a supported video card. SSDs are so cheap now, I'd recommend one of those too. But you should be able to get by with 8GB of Ram and just about any newer i3, i5 or i7, from the description you've given.
Here's a good link:
I made purchase of the following PC;
Lenovo P320 Tiny Thinkstation
Win 10 Pro 64 Bit
500 HDD SSD
16 MB RAM non ECC DDR4 SDRAM 2400MHz
Core i7 CPU i7-7700T (2,9 GHz (turbo boost to 3,8 GHz)
NVIDIA Quadro P600 2GB graphics board AND Intel HD 630 integrated Graphics board
Wireless network card (my preferred use on this installation) AND RJ45 network cable port ( I do not use)
2 display ports (look to only work with the integrated Intel HD630 Graphics)
4 mini display ports (seams to be connected to the additional installed Quadro graphics card) (this in the one I use)
6 USB 3 ports
Delivered with USB standard mouse AND keyboard w numerical AND safety/ anti theft lock wire with lock and key
I now have installed SW 2018 Student edition and I am pleased. SW runs fine and I think it will be good enough for my introduction into 3D Creations.
