Motherboard ATX help

[Alex_441]

I currently own a lenovo Ideacentre 510-08ish and purchased a geforce gtx 1050 ti 4gb. When I went to place the graphics card in it for not fix due to a small case size. How do I know what size atx my motherboard is to move my components into a new case?

Slim size PCs are not very upgradable due to custom non-standard size parts. Motherboard probably only fits the case it originally came in.

I suggest you start with a standard size bare PC case. You can buy standard size parts for these cases.
