ok, so I've grown a pair and Amigakit seem to have some in stock, so I've ordered one.
what's the best GFX card, or rather, what cards have people experience with?
I notice that you guys have Radeon's installed. it's not on the supported list? confused...
how are you finding it with heat, power, noise etc.
i'm looking for something not too noisy, and given the A4000's pathetic cooling, something not too hot.
my experience with AGP voodoo3's from way back when was that they got really hot!
is warp3d stuff supported on the radeons? i'm not looking at a voodoo4 or 5 as that's just a little bit far out regarding availability or even driver support.
I won't be using the GFX card as fast ram as I also have a couple of zorro ram cards on their way.
I've got a soundblaster128 somewhere, and ordered a 100Mb NIC - as all I have laying around these days are intel gigabit jobs. 
The mediator for the 3000 is intended for their mirage tower.
you want the radeon or a voodoo3 3000 ideally. make sure the A3000 has a buster 11 chip,since you will need it for zorro3 operation on the mediator. many machines came with buster7 which does not support zorro3 operation.Not sure if mediator works on buster9,but 11 is required i seem to think. note the mediator for the 3000 is not intended to fit a desktop,only a tower(their tower no longer sold?)..check into this carefully.
from elbox website:
'
The recommended configuration is: Amiga 3000D in Mirage 3000 tower case, any 68060 (or PPC with 68060) turbo card with 128MB RAM, a SharkPPC G3/G4 card with 256MB SDRAM, a Voodoo3 graphic card.'Honestly,i'd recommend a A4000 to do this in.the 4000DI version works well.The 4000di version will not fit the 3000
For those of you using 1200 mediators,since the A1200 has no zorro3(buster chip)the difference is the 1200 version has a tiny 8MB window and the A3000-4000 mediator has a 256/512MB window. That is one reason why the 3000/4000 board seem to handle anything with no glitches and problems even at res like 1920x12xx.
I've been running a 4000 mirage tower with mediator for many years nearly 24/7 and its been rock solid other than some crap ATX power supplies going bad.Good psu is worth the $$.
