CubiCubi 55 Inch Modern Computer Desk with Storage Shelves, Home Office Writing Study Desk, Simple Style Black - Perfect for Small Spaces, Gaming, and Remote Work

One of the biggest things I required was to ensure there was space for a mid tower and not flat on the floor, as the desk sits in a carpeted room.With almost 11K reviews and 95% approval rating, I took a chance on this desk. I don’t regret it.This is a particle board with a thin, steel frame, hence, it is not the strongest. As long as you expect for its placement to remain static, it is sturdy. Had all the boards sat on the steel frame like the main table top does, I have no doubt this would be 100% rigid with zero play. The fact that the shelves actually stabilize the structure on the side, explains the very minimal play/wiggle it does have.Make no mistake, if you taut everything finger tight, it will be solid, I DO NOT recommend using power tools. A manual, multi-bit screwdriver set is highly recommended, and it is what I used. As you can see in the pics, even finger tightening started sinking the frame at the screw holes.The shelves are indeed interchangeable. I’ve seen a couple reviews that say they are not, this is not correct. Just make sure everything is facing the side you desire and that the screw holes all line up on the side you wish them to be. I actually had to undo the tower shelf because I lined it up wrong the first time. I recommend you verify the alignment before putting everything together.I cannot verify how much weight it will hold up but my bare mid tower, a NZXT H5 Flow, is 15.5 lbs. and 36.4 lbs. with all the components. Unlike the shelves, the main table top sits on the frame rather than supporting it. Despite that, I am not risking ruining the desk to verify how much weight it will support. The monitor in the pics is hefty, 32 in., weighing approx. 35 - 40 lbs.Very quickly, I will say that lining things up can be a little difficult, but the very minor alignment issues are negligible and do not affect use in any negative way. (see pic).The width of the tower shelf is only 8 in. (approx. 204mm). My tower case is 8.94 in. (approx. 227mm) so it technically doesn’t fit. The feet are approx. .5 in. (half an inch or approx. 12.7mm) inward from the edge of the case so it does sit on the shelf (see pic). The height of the tower is also very compromised. At 18.27 in. (approx. 427mm), it does not allow for full towers and just enough for most mid towers, giving you approx. 19 in (about 483mm). Luckily though airflow is NOT compromised. That said, I would recommend a case that is longer, shorter, with 9 in width at the absolute max if you want to use this desk. This is of course assuming the feet of the selected case aren't at the edges of it, for best fit.Overall, I am very happy with this desk. It met all my needs, is sturdy, and enough extra space for a couple more things in the future. It is obvious from the pics that it is a great desk for limited space.
