Thanks for checking!
When I went straight to Punch Technology they quoted me £1,243 for:
i5-8600k
MSI Z370 SLI PLUS
GTX1060 6GB
16GB DDR4 2666Mhz Ram
256 M.2 SSD
2TB HDD
AIDOS 4 Heatpipe Cooler
Corsair VS550 PSU
Gigabyte Wireless AC Bluetooth
Windows 10 Home
It's a little less but with a lower end card, so I'm more tempted to go for the one on Ebuyer.
