Similarly, there's also Autumn's Descent:

Although, honestly, I prefer the versions of those songs which appeared on Deadletters.
If you manage to find the CD, then Under Midnight's second album,
Void, is another good choice. I was able to get it through one of the sellers on Amazon.
Neither of those are particularly punk influenced, either; I'm simply pulling out more or less chart-friendly Industrial Rock (among more well-known bands which fit that category are Stabbing Westward, Nine Inch Nails, Gravity Kills, KMFDM, some of Econoline Crush's output, Orgy, etc.). Some more entries from my iTunes purchases and other parts of my music collection:
Blind Faith and Envy (definitely not too hard, and much more in the Synthpop area)
Grand Theft Audio
Helalyn Flowers
generally, the
Blood & Chocolate soundtrack
Superlitio (the song "Lo-Fi" specifically - more like a modern take on early 90s dance-rock, actually; somewhat similar to the Candyland song "Fountain Of Youth", if you've ever heard that)
The GOTHsicles
For more of the lighter, more ethereal side, there's also The Last Dance, ThouShaltNot, VAST, and The Birthday Massacre (who actually provided one of MSI's "Straight To Video" remixes).
If you find you like Celldweller, then other associated acts like his former band, Circle Of Dust, Level (or lvl, as it's rendered now, apparently), Argyle Park, AP2, and Klank. However, some of those - like Klank, Argyle Park, and some of Circle Of Dust's earlier output - may be too hard for this as they're essentially Industrial Metal.
