Pictures can be seen on my "About My Computers" page (http://mikerye.homeip.net/about_my_computers.html). Some of the text and a couple of the pics (those of which showing GVP I/O Extenders which I don't have any more) are out of date. The top two sections of the page are how my computer room setup used to look. A bit of that is out of date. I have since rebuilt a bigger desk and re-arranged my entire computer room. The system information in THIS posting is correct.

Both systems are fully functional. They are running right now as I type this message. I don't have any videos made yet of them running, but I am going to work on that if I really decide to sell these systems.

So, with all that being said, what are your honest assessments of their worth?

@ SilvrDrgn

if you really have to sell then sell the A500 as the A4000T will be very very hard to replace when you decide you want it back (yes I said 'when';)). If anything do yourself a big favour and keep your CS-MKIII at least & if you MUST sell it don't settle for anything less than $1,000 USD for it

@SilvrDrgn,

I would never dream of selling my A2000 or A4000T-AT! I know I would regret it as they are both loaded.

So, I got a video made running MODs on each of them. The A4000T has a quite loud and annoying hard drive whine coming from it. Been doing that ever since I can remember setting that system up in its current config. I think it's coming from the Western Digital hard drive, but not sure. Anyway, it's quite prevalent in the video (the first link), so I filtered it on another copy of the same video (second link).
