Windows 7: Case Rollers

Somewhere I saw some rollers designed specifically for attaching to the bottom of the case, instead of using a rolling stand or table, but I have scoured the link history in my browser and can't find the location again. If I must, I shall go to Harbor Freight and buy some small casters, but I would prefer something more tasteful. Googling takes me mostly to some kind of laptop rolling bags or something else off the wall. Can anyone point me to the right location?

How about these:
Lian Li Industrial Co., Ltd.
a little expensive, but geez they look awesome!

Thanks, those are exactly what I had seen before and were looking for. They do look good, but that isn't the reason that I want them. They will go on my secondary rig, which will go under my L shaped desk, in the corner, which means that it will have to roll over the hump of the leg bases. I had a plastic rolling stand, but that only lasted until I tried to roll it out. Apparently, a roller got crosswise and broke off. This looks far more durable.

Where ever I saw them before, they also had them in black, but this puts me on the right track.

you're welcome
you may need to drill some extra holes in the baso of your case to fit it as there are 4 screws for each bracket - 8 in total. Make sure you don't get metal swarthe inside your case for it to get into your circuitry and short something out... If you're very careful, turn the case upside down, mark out the holes and sticky tape aerosol lids on the inside of the base where you're going to drill, make sure they're stuck on well and don't drill in too far

Good advise. I sent an email to the website where I thought that I saw these in black, so I'm going to await their response before jumping off.
