Whereby 'appliance' I mean like a network appliance such as a Firewall or a VPN that you can upgrade to a very low set minimum due to hardware expansion restrictions, perhaps more memory, or a WiFi card... but it does what it does, and is what it is without being able to be much more than that. ...Not like a blender.
The limited internal expansion capabilities of the G5 make it seem fairly similar to one of the firewalls we have in our datacenter at work. The firewall does its job, and does it well... As would the G5. But because of the expansion restrictions it will never be more than that.
I'd rather the G5 case be taller, or wider, or ANYTHING to allow even a reasonable amount of internal expansion. Expecting everyone who wants more space, or more optical drives, or more anything to buy external stuff to clutter your desk is ridiculous.
But that's just from a PC user's perspective, I suppose... So take it as a grain of salt. I'm just used to going out, buying another HD and plopping it in. Rather than going out, buying another HD, buy another hub to plug it in, wrestle through the jungle of cords to do so, then stack it on top the plethora of other crap plugged in to my computer. 😱
