They look good. Fit with the colour scheme well, but I would suggest making them a tad larger. The gap left by the old icon seems to have a lot of space.
I left them the same size as the old icons 24 x 23 pixels, but because the house took up most of the space it seemed larger. I did try with CPU's and RAM but I mentioned this in a PM to Sniper, I couldn't get them to look like anything other than a smudge at such a small size!
