I have this desk, it's part of a modular system at OfficeMax. You can always build your own, but I find I only build furniture that I know for sure I will keep for over 15 years OR that I need to have perfectly customized to meet my needs. Otherwise it's too expensive due to materials and time investment. My desk needs have changed over the past 5 years, when I moved from using CRTs to LCD monitors. Had I designed and built a desk around the CRTs, I might not have one that meets my needs today. How often to you re-arrange your office?

If I were to build one, though, I would create a fairly simple desk using a very heavy solid top. The top I made for my router table would work good here - it's just two pieces of 3/4" MDF glued together, banded by 1" maple strips and coverd in Formica. You can get Formica in all kinds of patterns/colors including woodgrain. I routed a 1/4" roundover on the edges to soften it. This would get you a waterproof, durable, cleanable and FREAKING HEAVY desk top. After that, legs or panels to hold the top up to the correct height and you're good to go. The top could even be curved (like my desk) and designed the same way since it's just MDF - it doesn't have to be rectangular.
