there are many variations dps-1200fb, dps-1200TB etc. Are all the same? also the breakout board fits all of them or there is specific designed breakout board for each variation?

Stick with DPS-1200FB, it's the most suitable PSU for your needs, IMO. There is plenty of breakout boards available for this model.

ok, so I am ready to order all the appropriate parts but as far as I understand, to make each of my rig work I need: a separate cheap 300w standard atx psu (about $20) just for the motherboard, a DPS-1200FB ($69) the cheapest I can find now on ebay (which is actually the DPS-1200FB-1, dont know if its the same) https://www.ebay.com/itm/HP-1200W-Power-Supply-578322-B21-579229-001-570451-001-570451-101-DPS-1200FB-1/232579507890?hash=item3626d1a6b2:g:81IAAOSwqiVaHttv to power 4x r9 290/390 gpus on each rig, a breakout board ($8.19) and the pci-e cables ($29.99) . Or instead of the standard atx psu, a pico psu adapter ($49) to power the motherboard from the server psu. Am I correct?
So, if I sum it all, the cost isn't so low as I initially thought. Its roughly $127. On newegg I can find some 1200W standard atx psus for the same amount of money and I will also have warranty. So whats the point to go for the server psu? https://www.newegg.com/Product/Product.aspx?Item=9SIA2J53KH0075
I need to setup about 16-17 rigs with 4x gpus each. So I am looking to keep the psu cost as low as possible but also to have reliability. Maybe there are some good server psu alternatives that are even cheaper and will do the job just fine or this is the cheapest I can go for my use?

For example I just found this monster on ebay for less cost than the DPS-1200FB. https://www.ebay.com/itm/Dell-PowerEdge-M1000e-Server-2700W-Switching-Power-Supply-E2700P-00-TJJ3M/302565706413?epid=21005587000&hash=item4672524aad:g:sDUAAOSw8UZaMw92
With this one I could feed 2 or 3 rigs at the same time, But are there any breakout boards for this? I cant find any
