Sorry RARRAF, how exactly would fitting the gpu be difficult, I'm not planning on using a high end graphics card and moreover I'm using the pc for very basic gaming. For games like gmod and others of that graphic intensity.
Ya the problem is finding a card. That's a SFF pc so most likely requires a half height card which are not very popular so not many are made not impossible though. You'd have to crack it open and measure to see how much room is inside your case.
The other problem is that it is a 6 ish year old dual core CPU with no upgrade path so it isn't worth getting a newer card for it. I wouldn't even consider anything better than maybe a
gt 710 certainly nothing more expensive than that though. That isn't guaranteed to work either but others have had success running it low wattage PSUs like yours.
It'd be one thing to retrofit an old thing you had laying around but I can hardly recommend buying a PC that old. It will likely play old games but nothing past the year 2000 roundabouts. Well maybe an indie game or two.
