All four of these cards have fan issues -- three of them stick, and then one has no fan at all. Make offers, separately or any combo:
1) AMD ATI Radeon HD 5870 1GB, s/n == 180948047131
2) (2x) AMD HD5830 Xtreme 1G GDDR5 (one has no fan at all, the other has sticking issues), p/n == 299-1E174-330SA
3) Same design as #2 above, except 5870, p/n 299-1E140-040BD
Pictures later / upon request
I bid 3 btc for the 2 HD5830s, assuming nothing is wrong with them but the fan.
