Hey guys, so I recently bought an HP prebuilt... I decided that I needed more power though and the integrated graphics aren't gonna cut it so I decided to get a GPU... The PSU ain't enough for a PSU so a new psu has to be added... The one installed though is proprietary so I also need a new Mobo as well... Given the fact that I must buy both a psu and a Mobo I decided to buy a new case as well since the gpu would restrict airflow in my tiny case a lot... So my question is... Can I actually make that work? Can I keep the CPU rams and disks and just buy a PSU a Mobo a case and the GPU and be ready to go?
