I really don't see any way to upgrade what you already have to what you need for the work you're trying to do. Minimum specs would be a hyperthreaded quad core with 32GB of RAM. Going by the ECS ECS > H61H2-M2
and Intel Sites Intel H61 Express Chipset Product Specifications it looks like you're limited to 16GBs ?? The i3 is a dual core hyperthreaded CPU and looking at the compatible chips Intel H61 Express Chipset Product Specifications the i5's aren't multi-threaded and upgrading to a https://www.amazon.com/Intel-Core-i7.../dp/B007SZ0EHE is Really Expensive so not worth the cost given the RAM limit.
My advice is to start saving to build a new Rig.
