Hi thanks all in advance. With help from a co worker I’ve made a shell of a pc desk. My problem is I have no vision or inner eye and can’t seem to figure out where to place my core components. My main issues are where to put the mother board and PSU with cable holes. I plan on have 280 air intake and euxaust. I’m not sure if I should do horseshoe direction air flow or back corners and go across. Also looking for a good usb3 expansion to use as a front IO and power bottun. Any link to materials , gromets , things to secure the equipment.
