Closest PC Motherboard Equivalent to the Intel iMac's Logicboard?

[Alvin777]

Hello Mac friends, just curious, would anyone know the closest PC motherboard equivalent (from any PC brand) of the logicboard of the Late 2015 iMac. Here is a detailed info on this iMac's logicboard (got it from an app through Windows Boot Camp). It's be interesting to know it's equivalent (and perhaps use the info for some future projects and upgrades):

Thank you.
