i have a couple of these and they work well. i don't see the semi enclosed trays like they used to have though.

yep, it's 3 ikea galant desks. 2 straight and one curve right. the bekant series replaced the galant series at ikea. they are similar but honestly i like the galant better as it's modular and has squared edges vs. rounded on the bekant.
i remember seeing your setup a while ago and i thought it looked nice. i honestly like it better than the door. regarding the wires - have you seen the wire trays they sell at ikea? they will fix your problem for cheap. i think they are 5-10 each and you'd probably need 3-4 of them.
the ikea website states that the legs carry a 10-year limited warranty, so you may want to check that out.
