I find it weird that a mobo designed with 4-5 PCI-e slots would not have the power support to use all of them? Surely if I was to line them all up directly on the mobo I would not have this problem?

The thing is that, no, motherboards aren’t engineered with the thought of having multiple video cards attached to them. Even having two Crossfired/SLI’d together is a fairly recent consumer demand. PCI-e slots can be used for all sorts of things (cap cards, wireless cards for external antennas, MIDI devices, breakout boxes, etc.)
Lining them all up on the motherboard directly poses two new problems: weight (on the board itself if parallel to the floor, stress on the PCI-e connectors if stood vertically) and heat dissipation (since the cards are going to be right up on each other creating pockets of heat that have nowhere to go, possibly damaging the cards).
Really, you just have to bite the bullet and either make them or buy them in order to do this right.
