Techradar posted a review on the ASRock Z68M-ITX/HT motherboard
A quote from the article:
We've been raving about Sandy Bridge ITX boards such as the ASRock Z68M-ITX/HT since they first appeared and quite frankly we make no apologies for it. If you want to build a small, compact PC with plenty of grunt then now's the right time. The boards even come with a x16 PCI-e slot so you can keep gaming.
