Based on the specs I'm finding for the Dell Poweredge T110 (first edition), you're not going to make that into a gaming system. If it only has physical PCI-Ex8 expansion slots, you're only going to be able to install PCI-Ex1 graphic cards. To my knowledge, they do not make consumer level PCI-Ex4/PCI-Ex8 graphic cards. If it does has a physical PCI-Ex16 slot (routed to x8), there may be a power (25 watt) limitation.
In either scenarios, you cannot install a decent gaming level graphics card.

A x16 card will work in an x8 slot, but will be limited to x8 speeds. PCI-e is backwards compatible. BTW, is it a full length SLOT ?
If I replace the motherboard with a "https://www.newegg.ca/p/1JW-003E-000E1?Description=lga1156&cm_re=lga1156-_-9SIAH3X7T20870-_-Product" from newegg would i be able to fit a good gaming GPU inside of it.
That's a mini-ITX board with next to no specifications know. It may not even be compatible with the case you're using.

You're going to need to check out your local markets (ebay/craigslist) for those. It's very unlikely you'll find any, New. I've been happy with my GA-H55M-S2V.

ThanksYou could, but the x1 limitation is going to be even worse than the x8 limitations. If you really want to build a decent gaming system, you'd be better off starting from scratch.
