I downsized my HTPC and I need to get rid of this gear before I can buy anything else (says the wife!! Argh!!). Anyway, as you can see in the picture, I've got a 3U HTPC case that holds 2 5.25" drives (comes with a 3.5" hot-swap bay -- taking up one of the 5.25" bays). Beyond that, it'll hold 5 more 3.5" drives, a MicroATX or Mini-ITX and a standard PSU. Great airflow with 80mm fans. --$50.
I also have two 3U vented shelves from Middle Atlantic. Perfect condition. --$30 each.
Lastly, I have one blank 3U faceplate and two Xbox 360 custom faceplates. They are for the old (non "Slim" version). Great for extenders!! --$5 each.
If you are in the San Francisco Bay Area, great! Otherwise I'll CONSIDER shipping the items to you. I will come back and update the listing as the items are bought, so assume they are still available.
