How it compares in Barebone PCs
Across the 47 rated barebone pcs products we track, the typical score is 4.5 out of 5. This one sits at 5.0, which puts it in the upper quarter of the category rather than level with it. Where almost everything is rated well, the gap at the top is small in points and large in practice. That places it second of the 47 we rank here.
It carries 26 ratings against a category median of 29. That is enough of a base to take the score seriously without treating it as settled.
On price it sits in the lower third of a category running from £4.99 to £5499, where the midpoint is about £47.02. Cheaper than most while rating at or above the category norm is the combination worth looking for, and it is the main argument for this one.
