I have an Osprey Atmos 35 from 2008, where you could insert a hydration bladder in the Airspeed air cavity. To attach a bladder to the pack, the Atmos has some small clips at the top of the cavity. Is there a place on this reservoir to fit those attachments? Thanks!

Yes, the handle at the top allows the standard small clips to wrap around it. I have a similar setup on one of my Osprey packs and it works great.

Allow me to speak up here. AKmtnbiker, if I understand you properly, you're speaking of the tiny side release clip in the Airspeed cavity from which you can hang a reservoir. The Osprey Hydraform res has a hole just above the cap that allows you to hang the res from that clip. It works great for that application. In most of Osprey's packs the reservoir can simply be slid into the sleeve that runs along the backpanel without any further securement.

Very interesting setup with putting the hydration bladder there. This reservoir does not have those clips you speak of. But the Hydraform is so easy to use anyway, you won't have to rig anything up like that. This will change the way you fill up and you'll wonder why it too so long for something like this to hit the market. If you did want to have this be on the outside of the pack though, you could Lace a compression strap or something through the handle. Good luck, hope this helped!
