So the other day me and some friends were talking I often make game servers on my gaming PC but it tends to be a little harsh on considering I run like 5 different servers so I ordered a mobo and a pair of xeon with the hopes of setting up a server PC I now only need a power supply and a gpu but this is where I am confused the mobo I ordered(https://m.ebay.com/itm/Genuine-Dell-Precision-Workstation-R5500-Server-Motherboard-FCLGA1366-HXJ1D-/202052845066?txnId=1587733155010) only has io risers which I am not familiar with how would I connect a gpu to this mobo and also what's a good psu for cheap to power two xeon e5606's
