I used to work at Ikea and I've seen all the desks and how durable they are and such things. That desks is adequate for a monitor / speakers / usual desk items. Be careful with a heavy case and never sit on it or use it to put your weight on, it wont break or snap but if its quite heavy it may cause it to bend and thus crack somewhat weakening it.
Thanks very much for the tip. I was thinking of buying it but I wont now as I doubt it will take my case and two monitors.
