I have been able to buy a Unifi Dream Machine Pro, 2x cheap (£29.99) switches that have 2x 10G SFP+ ports and 4x 2.5G RJ45 ports, 2x Unifi AC Lite AP's to give Wi-Fi to the house, 2x 10G SFP+ NIC's for my 2 servers, 4x 10G RJ45 SFP+ Modules, with also 2x TP Link Gigabit POE switches.
The 2 servers are going to have 10G between them, will make backing up the data from the Unraid server a lot faster.
The gaming PC's in the house will have 2.5G as they have onboard 2.5G cards, everything else will have a 1G connection.
