Ah forgot to mention, if you don't mind me asking how much do you reckon you'll be looking at in terms of materials cost?
As I've said in my OP I don't currently intend to build this, it was simply a design. Though I have an estimate of the materials needed and I've done a bit of math for anyone who thinks they'd like to build something similar.
NOT INCLUDING PC COMPONENTS, TOOLS, SHIPPING OR LABOUR
MDF SHEETING: 18x2440x1220 (x4) = £70
MDF SHEETING: 3x1829x607 (x2) = £15
PERSPEX: 3x1000x600 (x2) = £21
MDF PRIMER: 5l =£40
EGGSHELL PAINT: 5l = £50
HPTX MOTHERBOARD = £100
FAN FILTERS/COVERS = 120mm (x12) =£60
TOTAL = £356
This figure is however only an estimate, everyone makes mistakes when measuring and cutting, and other things like sandpaper should be factored in, paint figures are also estimates and that would be subject to change.
So basically...it'd be somewhere around £400 for the construction of the PC ready desk, which you could then install pre-existing pc components and watercooling into.
PS: Estimates for MDF and PAINT were from WICKES. Estimate for Perspex was from KITRONIX.
