My worksation is a full size desk I bought at iKea five or six years ago. (It replaced the pressboard computer table I bought for my Apple //c in 1985.) The desk features a recessed strage area designed for the CPU tower. There is a hole at the top for cable access (not large enough for even a small hand to pass through) which is of no utility for ventilation. So basically, I'm keeping my DP 1.4 in a wooden box, open only in the front. There is probably 1.5 to 2 inches on each side and maybe 6 inchs clearance on top (maybe an inch or two more.) It is hard to tell, but I think there is probably about 4 to 6 inches extra depth behind the CPU. Do I even have to ask if this is a bad idea vis a vis keeping the unit cool?
