One glaring omission, and one of the very few things we dislike about our X20E is the lack at least one drawer. I think the X23B may have the same issue. I've looked for ready made solutions that would fit in one of the pantry cabinets but it's such an odd size that we haven't been able to find anything. We ended up using some clunky baskets to store utensils and cooking tools.
I found a place that makes reasonably priced custom drawer boxes, Barker Door
. My new drawer boxes are 13" length, 8 4/16 " wide, and 3" deep on the box side. You have to take into account the width of the drawer slides. They come unassembled but are really easy to assemble.
Now keep in mind that I am no carpenter. Not by a long shot. The bottom drawer still isn't quite right, its a bit cock eyed, but it will do. I left some extra space between the bottom drawer and middle one to allow for spatualas and other things that are bulky and stick up. All in all this project cost me more than I wanted it to, but it was worth it. In total about $85 and maybe 3 hours work. I spent a lot of time making sure measurements were right before ordering, and the first drawer took an hour because I was being careful. This might take someone with experience less than an hour. Either way I think anyone with halfway reasonable skills can do this.
I cut these for mounting the drawer slides inside the cabinet.
