This is a large requirement, I can’t give you something for a tenner, but Scaleway.com offer very cheap dedicated servers, in which you can order more space, free backup, get addons like plesk, add more IP addresses, get a free /48 IPV6 block, and i’m not sure about raid
(I am not affiliated, I just once used them)
But I imagine you used InfinityFree and need more, it that case it wont be cheap, but somewhat near your specs are at Pricing | Scaleway, note that you cant get 4gb ram and 2x1TB, the lowest is 96gb ram, 2x 1tb, 750 mbit uplink. (You cannot get a virtual machine at your spec)
Please note: Windows OS Will and always will cost extra due to licensing costs, i recommend bring your own ISO and License
