I decided to use some shelf support pegs to keep the parts in place. This would give me maximum flexibility to move things around later..or even with another mobo then I would just drill new holes for the pegs to fit.
Finished...a brand new working bee.
Mobo: Asus Maximus VI Gene.
CPU: i7 4770K
RAM: G.Skill RipjawsX 16Gb 1600 CL9
HDD: Sandisk Ultra Plus 128GB.
Cooler: Corsair Hydro H90.
PSU: Corsair CX600M.
OC: currently at 4.5 Ghz, ~70c..still tinkering. This should be the new speed king of the farm.
Added a mobo fan, tucked cables in nicely, added handles...note the odd looking raised left side, coz of the connectors in the way...
