Making sure I purchase correct AirPort Extreme base station and cards

[ToTo Man]

I see 2 models of AirPort extreme currently listed in the Apple Refurb store.

Are either of these the current model being sold new by Apple for £142.00? If so then £41.00 is a pretty decent saving!

I'm looking to setup a home network with a USB hard drive connected to the extreme for centralised access to files over the network. So as well as the base station, I need to by 2 Extreme cards, one for my old G5 and one for my Mac Pro.

Can someone please confirm if these are the correct cards for my G5 (http://cgi.ebay.co.uk/ws/eBayISAPI....455968&ssPageName=STRK:MEWAX:IT#ht_500wt_956) and Mac Pro (http://cgi.ebay.co.uk/ws/eBayISAPI....157588&ssPageName=STRK:MEWAX:IT#ht_1211wt_941). Do I need to purchase a separate antenna for the Mac Pro?

Also, will my G5 be capable of g or n protocols or will it be limited to b? I'm pretty new to all of this!

I'll defer on some other stuff, but I think the AEBS with gigabit ethernet, that's marked at 101 pounds is the current gen model.

On the PMG5 side, the original Apple part for the G5 is the original Airport Extreme card, which is an 802.11b/g device. You'll be able to get an 802.11g connection with that and any generation of AEBS. Assuming the device has drivers (no experience with that 802.11n card), then if you get the PCI 802.11n card that you linked, and you get an 802.11n AEBS, then you should also be able to do 802.11n.

For the Extremes, neither are the current gen (model MC340B/A). You can tell by the model numbers in the URL. Refurbs have the "M" replaced by an "F" so the current gen refurbs would have a model number of FC340B/A (these don't exist). The 101 pound one is the FB053B/A model and the 109 pound one is the FB763B/A model. The 101 pound Extreme is non simultaneous dual-band, while the 109 pound Extreme is simultaneous dual-band, but previous model (no improved range, draft-N instead of final-N specs).
