I got lucky and found a huge desk that a computer store was getting rid of
for only $100. It's about 6'x30" and built out of an aluminum and carboard
honeycomb top that's terribly strong and yet lightweight.

I don't like not facing the door either; but ATM I find it far more useful
to face the windows looking out over my driveway and front yard.

I tend to pile my computers and other crap onto wire racking like this stuff:

it's not fashionable; but it is strong and good for cooling.
