I didn't used to care, but I hurt my back a few years ago and it's been acting up recently - so it's on my mind. I have a sturdy folding table that I usually lift my PCs up to for repairs/tweaking. Maybe I should just mount the 800D to an air lift and adjust the height as needed :sneaky:
If it's only about moving it for periodic maintenance, service or an ongoing modding evolution, I wouldn't know how to answer that. I can see there are times you just have to lift it up. For me, the most I ever did that after the hardware was in the case was to lift this or that computer up on a very solid glass-slab coffee-table. Sometimes -- I just flip it on the floor after I've spent some time thinking about what I'm going to do -- so I don't strain my back. My solution: I stopped thinking about large drive arrays in workstations, or the difference between SSD and HDD weight. So my heaviest system is my server.
But suppose you didn't mind spending maybe $60.
In the industrial section of many towns or cities, there is usually a "metal-supply" warehouse. The have a large yard, with corrugated iron shelters and bins for various sizes, pieces, shapes and metal types. They often have precut pieces of aluminum and steel. There is a standard 2"x1/4" metal bar, which you'd ask to have cut to 12" lengths, but I'd found they have bins with these sizes in the rear of the store-front. In the store-front, they sell tools, and you could probably pick up a $5 drill-tap kit for a 6-32 screw, or for any screw size you preferred. the 6-32 Is a standard computer case screw shipped with PSUs, and used to secure rubber feet to the bottom of some cases.
There's a web-available hardware store somewhere in Ohio or Indiana called Lawless Hardware. They have extensive menus, but there's a category for "casters and wheels." The casters you're looking for would be of various wheel diameter -- I had put a 3.5" dia double braked casters on a Compaq server case ('95) once. That sucker was heavy! Get the casters with the square mounting plate, likely to accommodate 4 stubby 6-32 screws.
Cut the aluminum bars with a hacksaw and clamp to exactly the width of the case bottom. [Or -- you could extend the "feet" and wheels on either side -- for whatever practical or aesthetic reason.] Precisely mark and drill holes for the four screws of each wheel on each end of the aluminum bar. Tap these holes for the thread of the 6-32 screws.
With the right case and a little luck, you should be able to remove the rubber feet on the bottom of the case. After drilling two more slightly oversize (> 6-32) holes properly measured for the case's screw-taps for the rubber feet, use the case's threaded holes to secure a bar at front and case-rear, each fitted with two of the caster wheels.
Now you go out to MNPC Tech (
http://mnpctech.com ) and buy a pair of aluminum billet or similar handles from their categories. You only need drill holes in the case-top to install them with their sturdy hardware parts.
You can roll it, lift it, dance it around . . .
