If he hadn't used the words 'Old School' and 'Collectable' (and then saying it's ready for upgrades, which kinda makes the previous words redundant), then maybe.
Theres always some dreamers out there though! (in Micro Mart a little while ago there was one person wanting £500 for a Pentium 166 for instance)
Sometimes at work I get asked what the value of redundant stuff is, as they want to buy it - most seem to greatly over-value it!
