Here's a knock off Alex drawer on Amazon. Supposed to be 26 inches tall, but maybe higher with the wheels?
I got some from Amazon that are pretty much identical:
There are things like this
Look into art-supply things as well
“furniture” type things like lingerie chests
Thank! I did some quick research and found this drawer unit on Amazon that looks pretty similar to the Alex. It seems to be a bit shorter than the Ikea version without the casters, so you might want to space the desk surface out from the top of the drawer similar to this setup from RandomFrankP. You can use some small furniture legs like this to achieve a similar result.
The price must have gone up, I ordered them a few months ago and they were less than $70 at that time. Keep your on eye on them, Amazon prices fluctuate frequently in my experience.
