I need some more hard drive, you are providing small hard space for my needs, I'd need to run Bitcoin full node so it's more than 160GB at least and

For RAM 2GB is kind of enough but no single CPU core, Bitcoin Core is better to install on 2-4 CPU cores. since you are buying dedicated servers you can

Isolate whatever of the resources, could you price a 200GB HD 2GB RAM 2cores CPU with the same internet speed as other plans? just give me a price

And I will buy 6 from you for 1 month as a test and will get them for one year if they are as good as you say.
