Looks a bit shonky to me, but if it works, good for you. I worked for a design agency back in about 2004 which had the same sort of infrastructure internally.

Looks a bit shonky to me, but if it works, good for you. I worked for a design agency back in about 2004 which had the same sort of infrastructure internally. They had a cheap desktop Exchange 2003 box, cheap desktop Fileserver, cheap desktop SQL + App server, cheap desktop mp3 server, big old DLT drive, SDSL router, switch, a KVM, cranky old monitor, keyboard, mouse, mounds of cable, a well underpowered UPS and a garfield all wedged under a couple of tables. Some muppet knocked over a coffee cup and it spilled through the gap between the tables into the monitor causing a cascade failure and a small fire which melted pretty much everything under the table. It took the company out for 2 weeks until Dell could ship new kit in. There is a reason to do it properly IMHO (and experience!)
