Well, I just finished putting in the window in my SX830. I bought the rectange window kit from PcMods.com. I ended up putting it just to the right of the latch because I didn't feel that confident in making curves around the latch. I started cutting with my dremel and reinforced cutoff wheels, but that was taking forever, so I switched to my Jig Saw... let me say, that worked WONDERFULLY. I was worried that it wouldn't be a direct view of the CPU and mobo, but thats only if you look straight on. If you look at a slight angle, you can see everything in there. Looking straight on, as far as you can see to the left is the northbridge. Regardless, it looks great, and was much easier than I anticipated, this being my first mod. The other nice thing about the window position is that the area to the left of the window and below the latch is a PERFECT spot for a blow hole... I don't have a digital camera, but I'll try to get some pics scanned in..
