Hello all, I have recently purchased a HP pro 3010 mt and I was wondering if I could upgrade it by installing a graphics card. Here is the PC I bought and my main concern would be that it wouldn't fit inside it. http://www.ebay.co.uk/itm/181382061874?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Get the length measurement specification from the vendor of the card you intend purchasing and research or ask seller to give you amount of space available in videocard mount area to hdd cage for any case.
+1 - If the machine does not already have a graphics card, and in many cases even if it does, HP and other OEM mfg's use the mimimum psu required for the original configuration, so it is likely you would need a new psu when adding a graphics card.
