there's an HIS low profile 7750, amazon also has ddr2 for sale or you could try ebay from a good seller, just make sure not to get the wrong type ram from china...I only get from USA sellers
HIS has FAT cooler, protruding too far making this card almost dual, it might not fit.
There are only small pictures out there, let me show what I have found (I seen this HIS card, but omitted for that reason, LOL)
This is good video to observe
http://www.youtube.com/watch?v=iunWTyz-Vik it is about XPS 200, but XPS 210 has the same architecture
So HIS fans might touch hard drive, leaving very little space for air to move around, other than this, HIS card looks very good.
