I thought the same thing so I used heat safe electric tape on the back sides just to be safe. 
1. Find old inexpensive laptop on ebay
2. tear apart
3. make picture frame.
Got my first 3 steps on my to do list now! Now to find the old laptop!!! :-D
I think i need to design a really sweet designerly frame though... perhaps I can combine this into something neat for my portfolio....
this is SWEEEEET
ps. are those wood slats the velcro is on? aren't you a little worried with the wood next to the computer parts? heat wise? I guess it wouldn't get too hot just slideshowing....
