Server prices vs Desktop prices

[silverzx]

personally for server use you have to be careful about RCDs in the system and different ring mains when using ethernet over powerlines,
ie on the same ring main its fine, but we had issues with it in my house (all brand new electrics) as it was going through 2 seperate RCDs for each ring main, when connecting the modem downstairs, with the PC equipment upstairs.

i ended up running 2 Cat5 cables upstairs, one into the office and one into the loft (which now runs our CCTV system), via 2 sockets on the wall at each end (single socket with 2 plugs) to use

Sorry, what?
