Sony DRU-870S 24x DVDRW SATA Black - Retail Box £20
Antec Mini P180 Black MATX Case - No PSU £60
Corsair 400W CX PSU - 12cm Fan 80Plus Certified Efficiency 6x SATA 1x PCI-E £40
I will also be buying a dedicated graphics card later when the new directx 11 range comes out.
Is everything compatible.

Hmm if i were you i'd tone down on the case as that seems a tad steep for an mATX case while with the funds saved, i would pump into a more powerful PSU (assuming you plan to game with powerful current gen GPUs)
save £15 and get an antec 300 over the P180 as it's not much taller.
and get a 650w from corsair, OCZ or Antec if you plan on getting a DX11 graphics card.
