The highest performing low profile card will be a Radeon HD 5670:

775MHz with 400 Stream Processors

Compare to a 5770 - at 850MHz with 800 Stream processors, a 5770 gets 220Mhash/s, so expect around 100Mhash/s from a 5670. Which is currently about .04 BTC a day.

This card doesn't require a PCIe power connector, but it's power rating is 65 watts, so it may or may not shut down the Dell's power supply once you fire up a Bitcoin miner after adding this card.

Actually, theres a better one. 6670. 480 SPU's @ 800MHz, single slot lower profile. http://www.newegg.com/Product/Product.aspx?Item=N82E16814131469

5670 = 400 SPU @ 775MHz
6670 = 480 SPU @ 800MHz

You're still talking about 120MH/s TOPS.

Hi,
It is one of those compact pcs so it has to be low profile.
Any suggestions welcome

i got a 5870 in a computer with an 80plus gold 450w rosewill capstone, and I overvolted it a hefty amount (1.213v, compared to 1.163v normally), it consumes 238 watts while mining. so you can probably put any high end single gpu card in there and be fine. of course, low profile cards will consume much less power if you want to only do low profile.

I have managed to acquire one of these computers, but it has onboard graphics I think it is limited to low-profile PCIe 16x video cards. The power supply is only 280 watts (external).
Can someone confirm if this is correct, what graphics card I can upgrade to and if it would be worthwhile?

I have free electricity and would like to run this to generate a few extra BTCs if possible.
