As the title says it would be nice for servers to cables be hidden with RedPower Covers,etc.
Reasons?
Avoid Huge Cable intersections making solar arrays.
Allow IC cable being used on walls (you could make your machines near wall [with cable inside it] {need RP}
Easy hiding of IC wiring,and stuff
Easy way to avoid tin cables connecting other types of cable
Or make tin cables paintable, since they cant be insulated and makes lots of intersections on solar arrays, which cause CPU problems on servers.
