If you aren't planning on recessing your machine you need to analyze if you can sew that way. Do you use a recessed machine now? If not, do you have issues with sore shoulders and/or back? Check the height of the desk.
I sewed for years without my machine recessed and always had shoulders/back issues. Finally got an inexpensive table that recessed my machine. Made all the difference. I still may get sore but that's only if I stay at the machine too long. Otherwise I'm fine.
Something to think about.
