Hey guys, I recently bought an old HP OEM computer (a 'dc7700', I think) off eBay. It's one of those towers that is placed horizontally, and it's quite thin. I was planning on using it as an HTPC but it lags when trying to watch HD movies, so I think I'm going to buy some really low-end graphics card. I was looking at this one (I'm in Australia and it's either eBay or local IT shops): http://www.ebay.com.au/itm/Asus-ATi..._Components&hash=item19c5f77a3f#ht_1134wt_936 I'm wondering, will this fit in the tower? Do I need to specifically look for a low-profile graphics card? Thanks in advance.
