It's the Lenovo E50 preloaded with Win 8.1 with Bing [Build 9600]

£119 for a reasonable quality budget PC,
including fair quality USB mouse & keyboard.

[damn good bargain; bought two -
but - Ebuyer is the shitest online shop with the worst customer service I've ever encountered... I'll never buy from them again...]

Lenovo has loaded a "One Key Recovery", so providing it works - that should be the safety net
to roll back to factory reset
if for any reason I can't stand win 10...
