Single Slot GPU

[SavellM]

I've been given a server, damn good one.
Its a Dell R410, with 32gb Ram, 2x Xeon X5650 Processors (2.66GHz, 6C, 12M Cache), has 500w redundant psu.

So Im thinking about using it for gaming too.
I would guess (I have not got the server yet) that it would only take a low profile single slot GPU.
Im wondering what the absolute best one I can get is?

I have seen the Afox AF6850-1024D5S1 which looks good as it doesnt require any extra power, and its small but cannot find it in the UK!
There is a PowerColor AX6850 1GBD5-I2DH which looks good.
But requires extra power which im not 100% sure is available.

Any thoughts?
What about an Nvidia equivalent?

ah man!
Cannot sell it, need it for work.
But wanted to use it for 2 purposes
Will take a look once it arrives at the space

If I cook it I cook it.
Its under warranty so not too worried atm

Will have a play once it arrives and then see about space.

Hoping a low profile single slot GPU will work.
