60w PSU enough for this system?

Ok, it's come time for my to rebuild my second/Linux system. Given that this system is always on, but is often used more for background tasks and simple usage rather than mainstream use, the qualities that I'm prioritizing here are small size, quietness, and low power draw, rather than raw speed (though I don't want something that drags too much). I already have my bigger and power hungry system for games and such :).

One major requirement here is DVI video output as I have to have that to hook to my KVM switch.

So, right now I'm looking into Mini-ITX systems. Preferably something with an external power brick to save space inside the case as well as avoid the need to add a PSU fan. I looked at several Atom based systems, but they a) were slow even for my intended use, and b) the few that had DVI video output also used an apparently warm Northbridge chip that required a really buzzy 40mm cooling fan that a lot of people didn't like.

After some looking I settled on the following:

Intel Celeron Conroe-L 1.8Ghz 35W CPU
Zotac NF630I-E LGA 775 GeForce 7100 Mini ITX Mobo
Rendition by Crucial 2GB DDR2 RAM
Seagate 120GB SATA 2.5" Notebook Hard Drive
LITE-ON Slim 8x DVD Burner IDE

Everything looking great, but the case I want (Apex MW-100) includes a power brick that's only 60W. I would have felt a LOT more comfortable with 90W or more, but seems that everything with a bigger unit brings it back into the system meaning bigger case and a PSU fan to contend with. I have a second choice that has a 120W PSU (the Inwin BM639), but it is a bit larger than my first choice.

My basic question is: do you guys think that the above hardware would work within the confines of the 60W PSU, or would I run into issues?

Anyways, sorry for long post. Thanks for any advice.

I think 60W will be enough. Notebook drives take little power and the CPU is a sipper as well. I'd say your setup will idle around 40W and load around 60W from the wall.
