Ok so i want to build one but i have no clue with these small form factor pcs. i know my **** with normal pcs etc but ive allways been confused when it comes to these mofo's. i see there prices ranging from £50 to £200 - what do you actually get? cause the websites im looking at are not thatr clear. Bassically im looking for what do you get with these cubes? i wanna get one for lans, i need the mobo to have PCI-E for my x800 and ddr 400 Ram complatible mobo.
