Yeah I don't know about special, but they're certainly rare. The hardtail particularly so. The [more] modern Quakes and Mount Visions are pretty common though so if you're thinking of selling you won't get £trillions I'm afraid.
To be honest, the hardtail I owned wasn't that great to ride! It was super stiff; almost unbelievably so, and was pretty heavy as far as frames go. I think if I found a cheap frame on eBay I'd probably use it as wall decoration rather than trail hack!
But a full sus with XT/bonty and HS33s sounds like a good bike to me; enjoy it!
