Sounds like a good deal..
How much is IT going to sell it to you for? Please note: Ward and I have the same single-quad core mac pro.. mine was originally a 2.66 and his is a 2.93, however... I went one step further.. I upgraded my processor to the W3580 which is apple's top of the line going for 3300.00!!
And you can also do the same as well.. so while the machine sounds like a great deal, you just need to beef it up a little. get rid of the GT120 and replace with a 4870 HD, or GTX 285.. also, see if it has built in airport. Refurb machines and mostly newer ones usually don't come with airport installed unless you request it through BTO(new mac pro), but refurbs don't usually come with it. However, Ward was lucky as the person who originally owned the machine got airport installed. Apple didn't bother taking it out.
Ram looks good.. 8GB is nice, though you will get better performance if you install memory in 3's rather than 4's. DDR3 is triple channel for faster performance, though many suggest on here that you won't notice the difference if you have the 4th slot filled or not.
Lastly, consider the w3580 or i7-975 processor.. both can be had for under 600 from velocitymicro.com - thats where I got mine and it runs great. Please note: if you go the desktop i7 route, you will need to remove ecc memory as ecc isn't supported on the i7.. w3580 is xeon and the existing memory can be used.
If they are selling it to you for under 2000.00, I'd grab it. Refurb cost me 2199 + shipping and tax. At least you don't have to worry about shipping or tax.
A business near me is going out of business and are selling their stack of mac pros.
