A:AnswerIf you're talking about the Small Form Factor version of the 8300, yes. If you're talking about the Tower or Mini Tower versions, they are large enough to accommodate larger Graphics Cards. If you're asking about the 8300 Micro, then no.
A:AnswerThis card is better suited to being used on an Business Class machine where you need a better graphics card than the typical Intel card found on these machines but you're limited by the form factor or power issues found on the smaller Business Desktops. If you want something better suited for gaming, I would suggest looking for the Low-profile cards offered by ASUS or even some of the Low-Profile GTX 1050s on the market.
