10Gbps.io can provide you CPU 2xE5-2620, 16GB RAM+, any drives as you need with dedicated 1Gbps port, prices around $300. In case it's interesting for you ask them more on chat.
Its good to see a international seller on R10. If you can make some private offers for R10 users on new topic, that would be great.
I know your focus about 10Gbit connection, but its very high amount for most r10 users. Maybe you can a bit low spec offers like 1Gbit unmetered or 3unmetered like OVH etc.
I'm sorry about my English, i'm not native English speaker but i hope, you can understand me.
