My brain was so hyper focused on the RAM I missed the HDD.

Honestly you can just get this 2TB NVME for $75. The brand may seem like an off one, but I've had the same SP 1TB boot drive for 4 years ago and it still is reporting good health with constant use (I use this for work and gaming, so my PC is basically on all day).

Tagging u/Phased_xd so he can see this as well.
