would it be possible to chain approximately 125 Radeon r9 280x's together or in groups of 5 per motherboard with two psus each? I'm very new to gpu/alt coin mining but a friend of mine eagerly wants to get into the mining field. He is willing to give me the money to pay for about 25-26 5 card rigs and the respective hardware to go with it all. In a way I guess he is a venture capitalist. We were just talking about it and I explained to him how crypto currencies work and he said he would like to give it a shot.
I could setup a small 5-6 card rig without assistance but my main question is how can I configure multiple groups together or into one large group? And would anyone be willing to lend a hand and walk me through setting it up?

Big issue is going to be finding a place that can provide you with that level of power and also mitigate the heat generated...and deal with all of this in time to actually turn a profit.

Setting your own pool up is not necessary at all. It does have benefits but disadvantages as well.
But your biggest issues will be - as said above by calculatorduck - power consumption and heat. You need a place that provide you with enough electricity, it can be ventillated, the noise is not an issue and it's secure.
All in all, it's a rabbit hole you're looking to go down into and your best bet is to plan everything ahead.
Regarding the rigs, you probably should use a combination of components that are being used and established by miners on that scale and copy their setup. Buy one or two rigs, and if everything's fine then scale up.

You have to think about all the extra expenses that will increase ROI time and the fact that hash rate will continue to rise over the coming months, also eventually ether will be going POS so hardware mining will be eliminated. Of course it is possible and really not THAT hard to setup..depending on your skill level and you will want to have your own node to do solo mining to earn the most. But no one wants to see diff rise more than it already is, so don't expect someone to hold your hand through the setup without paying them.
You need a facility, cooling, proper power, networking, cabling and of course all the hardware.
R9 280x Watts = 300 so 125 x 300 = 37.5 kw factor in PSU efficiency of 90% = 41 KW roughly.. so for cooling...
The gpu & psu will produce 140'500 btu's of heat and will need 11.7 tons of cooling and I didn't factor in the mainboard/cpu
As for power a normal 200 amp breaker can provide 24 kw of power, so were talking serous electrical work.
And then at any moment the GPU mining scene could go *POOF* no more profit and how liquid will all these assets be?

what 280x consume 300? lol you can downclock it or downvolt for 200watt and maybe lower, 300 is overestimate, so you need like 24kw in total power i would not worry about gpu scene being not profitable, there is always something to mine, i remember they were saying same thing each time the profitability rise to the sky and look now it's again profitable

i would avoid a pool, i would simply use many instances of teamviewer to contorl them all, you need only few click, but if you want this to be more easy you can try cgwatcher

And ethereum wasn't even profitable until a couple of months ago really.
