Pondering if its worth putting my 1200 in a tower ?
How much work and fuss is it ?
Any significant gains ? I imagine the biggest deal is that its easier to cram stuff in there.
How much money am I looking at ?
I have 2 x A1200 towers gathering dust. To be honest, if you want easy expansion of your A1200 then get a USB controller and hook it up to your clockport. You can hang ethernet, hard drives, DVD-RW drives, memory sticks, SD/CF card readers, sound cards, etc off that.
Now, if you want to upgrade your graphics then I would go for the tower but only if you want to add a PCI busboard (Mediator, etc), although I'd still get the USB controller too. I stuck a no-name Virge card ripped out of an old PC into my A4000 Mediator and the speed on Workbench for opening folders, displaying icons and sliding windows around is fantastic.
