Okay, so I'm going to be building my own computer desk. I just got a new tablet PC, and along with my 22" monitor, three speakers and sound control station, it won't fit on my current crappy desk. I'd been putting off replacing it because I couldn't find one I liked enough. Now I've decided to build my own. I want it to match my theme so far--I have Logitech Z5500's, a Samsung 226 BW and a flat black and gray keyboard and mouse. I'm thinking clear (no tinting), black and chrome (with very sparse blue LEDs) as the only colors I'll use. I like the glass desks, but I'd like one with metal backing (I'm going to be doing a custom vinyl graphic on the back of the glass/plexi/whatever, and I want the (polished black) metal behind it for contrast. So, I haven't worked much with acrylic, plexi and glass before, and I was uncertain which to use. I've heard acrylic scratches easily, so that's out, but I'm not sure if plexi will be much better. Meanwhile, glass would work, but the desk will be 5' or 6' long, so I'd like to avoid the trouble of mounting it without breaking it if at all possible. Would plexi be sufficient? Or would I be better to go with a different material altogether? I don't know much about polycarbonate and other plastic variants. The good news is, I don't need to do much with it. Just a flat plate, with a grand total of six holes drilled in it (for legs and a cable management panel) and no bending at all. It does need to be scratch resistant and as clear and glass-like as possible. Can anybody give me some pointers?
