wat's that 4 short sticks of kaki screwed on the 4 edge of mobo screw holes,
to make the mobo stand/floated when placed on flat surface,

is it custom made, or can buy elsewhere'

wat i can think of are,

1) save space alot!! if you got a simply+small 2 level rack.
top put mobo, btm put psu, hdd, drive, etc.
so, u got a size of ur mobo + 25cm height, cubic vol. for entire rig.
screw 4 roller wheels on btm legs, for easier moving around.

2) can have a ultra short loop for wc setup.

3) for temporary benching, or upgraditis will find it much easier for them.

that's sick'
you used what to korek ur table to bore hole?!?!

and did i see a diy water block?
that's an alu. heatsink sealed by acrylic = waterblock?
