Question Need advice on replacing my Alienware Alpha R2 console

[Samduhman]

Any hardware guru's here that can provide some guidance on replacing my Alienware Alpha R2? I've been using it as a home pc for streaming, NAS access and light gaming? Lately its been booting and pausing with a drive error. I restart and it comes up fine. I figured it might be a good time to just go ahead and replace it.

Specs:
CPU: Intel Core i7 6700T
GPU: Nvidia GTX 960 4GB
RAM 16GB DDR4

I'm assuming one of those new mini PCs would be perfect but looking at the specs I can't figure out their actual capability compared to the Alpha R2.

Basically I would like the replacement to provide at least a 50% increase in overall performance (including gaming) over the Alpha R2. Is that doable for $200 to say $350 with a mini PC? The cheaper the better. I'm not looking to invest to much.

What sort of streaming? You might want to mention all the app's and games you're currently taxing the system with.

For the sake of relevance, what are you currently looking at?
