The link you provided is to the Alphacool Eisstation DC-LT - Solo Mini, not the Eisstation 40 DC-LT-Reservoir. The links in the first sentence are to PDF manuals from Alphacool for these two parts. The dimensions of the Solo Top are 50.62 m x 50.62 mm x 37.2 mm. This is clearly listed on the Taobao webpage your link goes to. The Solo Mini is a pump top for the DC-LT line of pumps and was made small enough to fit in a 1U server rack. The 40 DC-LT Reservoir is larger: 60.0 mm x 40.0 mm x 36.5 mm because it is a pump top and very small reservoir (~ 28.7 ml !)
