I think it looks fantastic, gets quite highly praised by places like SPCR.
Keep in mind you will need an m-itx motherboard like the Zotac 9300, space for a cooler and graphics card will be limited and you'll need a Pico psu (150w available) and external power brick.
I would spec you something but OcUKs choices are a little limited, however look at the Zotac nForce 630i-ITX Motherboard, a pci-e 1x TV tuner and e5200/5300 or similar CPU.
