In-Win manufactures a curious mix of PC cases. In the past we have seen basic (but worthy) Mini-ITX cases such as the BL641 and more recently the GR One gaming tower and GT1 (as seen in our Falcon PC review). Then we come to the In-Win Signature Products which include the £320 D-Frame and this £249.95 D-Frame Mini. It’s an open system that is constructed from welded aluminium tubes with smoked tempered glass panels on both side. The result is a visual delight. The chassis we saw is black with red silicon bumpers. Alternatively you can have red with black bumpers or orange with blue bumpers which may sound foul but actually looks amazing.
