I second that.@dondan i think that the pre drilled rubber holes are not important at all. Here is why.
You need a 90 degree fittings and radiator placed at the bottom.
Radiators have different spacing between G 1/4 inch ports and even tho the fitting can be rotated, the tubing will kink and stop the flow.
If user need external rad/pump/chiller they can drill holes themselves, as they probably know their way arround modding if they want external enclousure.
Of course this is just my OP, and the survey will show what users preffer.
I believe a NZXT Kraken X52 (the largest AIO pump to my knowledge) would fit since the space left is 54mm and the pump is 52.9mm.I wonder if the 2.5 slot configuration would allow for the taller pumps you see on a lot of current gen AIO coolers. Or even this:
What's the point in a bifurcated riser when you'll never fit 2 GPUs into that? (well I guess there's a 1slot gtx 1050ti, but yeah..)Radical idea here, @dondan: I like the idea for the 2/2.5-slot riser. It's (almost) idiot-proof. But how about a BIFURCATED riser with each slot x8? No current GPU saturates x16 anyway, but it would require using a motherboard that supported bifurcation. Fortunately, many more do now.
I'll take a stab: The intake for the PSU is on 1 side or the other (guessing the side panel of the case), so the PSU exhaust direction doesn't matter - it shouldn't interfere with the exhaust fans on the bottom, and the PSU always gets fresh air..@dondan, How does the airflow go with the PSU? That picture looks like the PSU is venting air upwards, although the air is getting pulled downwards by the case/radiator fans at the bottom.
I guess just mounting the PSU with the power plug facing down would work, unless it needs to be in that specific orientation due to cables, etc.
