If your USB ports are too close together on that hub, then a triangular hub would certainly help. That is the idea behind the Trust 4 Port Triangular USB Hub. There are two ports on either side of the triangle, back hold the power & PC connection, along with two USB ports on the top. The top mounted ports will also enhance your wireless performance, if you even have a WUSB device, but definitely a benefit for Bluetooth and mouse receiver dongles. The 4 Port Triangular USB Hub (HU-4840) supports both 1.1, 2.0 Full and 2.0 High Speed.
