Think this would be solid as a server rack?

I'm playing around with different server rack designs made out of 2x4 and 2x6 and would like to get some opinion from people more experienced working with wood/server racks to make sure I'm on track and also within spec.

http://gal.redsquirrel.me/imag...ack%20design%20(1).jpg

I was going to just drill all the holes but think that would really weaken the wood as all these holes would be very close together, so rather then install rail kits I would just lay the server on the rails.

In 80% of the cases I wont even be using rack mount equipment and will just put a 1/2 inch plywood sheet in the rails. But from now on I will probably buy rackmount. I will most likely build my own cases as there are not many nice rack mount cases. (I want 10+ drive bays and whole shebang).

Each slot is 2U and because of my design I will loose the height of a 2x2 per 2U section but way I see it is it will act as a bit of ventilation, not good to over stack servers anyway, and I really don't see myself totally filling this rack.

My only fear is this design might be wobly on the sides due to my lack of triangles. Do you think this may be the case or will the 2x6 on front and back help? The 4 main frames are L shapped.

I would use wood screws for this (probably same you'd use for a deck).

Also would I get issues with heat causing the wood to resize? Or would that be very minimal? I'd paint it, if it matters.

Also the sides would be plywood but I'd make them removable. The top will be screwed in plywood to direct the heat out (probably to a vent with a blower that will push it through a duct). The front will probably stay open, but I might add a door that is ventilated.

Any input will be appreciated, thanks.

Oh and measurements are in cm.

Why not just buy a used rack system? All that wood will be heavy as f' and you'd have really bad ventilation ...

Server racks are upwards of 2k. This will be cheaper even considering I'll have to buy some tools that I don't own, such as a skill saw and maybe a mitre saw for the angle cuts. My first build so I might screw up and need to buy extra wood. Plywood is expensive though... but I may use cheaper stuff for the sides.

Ventilation wise, I'll have a blower on top. Probably a furnace blower, but I need to research that more. I don't want TOO much power or the air will just bypass the servers altogether.

Also shipping a server rack would be very expensive too, so even if I get a good deal.

Wood is probably a poor choice of material. It expands and contracts with temperature and is quite the insulator.

two grand? How do you figure that?

http://www.rackmountsolutions....4_Post_Server_Rack.asp

For just the bare four posts are just a few hundred dollars new, so I would think used one are readily half that. Shelves are less than a hundred bucks new.

The end result I also think wouldn't be that great using wood. I also vote for skipping making one and buying a used one off craigslist.

How would a rack be shipped from states to Canada? Something that size and weight would cost an arm and a leg to ship. Also I rather not have used as you never know what condition it might be in, or if it's even real. Could be a scammer etc. I avoid buying used stuff online.

And I checked various places like Dell and IBM and they are all upwards 2k. Found one on tigerdirect for 1kish. I want it enclosed so I can better control air flow (hot isle/cold isle principle) and also for noise reduction (the room itself will be insulated so that part is not a HUGE issue)

Start adding PDUs and other features and it's all extra too. Even the side panels are often extra. I will just make my own PDU with about 12 receptables per side (max the code will allow as this may count as a permanent installation).

I'm also a fan of the used route. Wood's just so bulky for the same strength.

We just sold one on craigslist for $50, took two weeks to sell the damn thing too.

They don't have to come standing upright... most simple 4 post racks come in a couple of boxes and get put together with nuts & bolts.

Now if you're talking about a fully enclosed cabinet with fans, a PDU, cable risers etc then obviously it's not going to be cheap. I would find a vendor who sells 4 post racks who also sells cabinets and accessories to match it and upgrade as you see fit.

With tools and materials you have to buy along with the time invested in learning how to build something (I'm assuming you aren't a wood working expert) you're better off buying a used real server rack.

Wood is also a very poor choice of building materials for this type of installation.

I can see that and somewhat agree but its a rack. Its a big chunk or metal not much can go wrong with it. Kinda like buying dumbells\weights not much to go wrong. Also when buying local you can check out the item in question before handing over the $$$.

Also, if you want a completely enclosed rack for better cooling wood is not going to be a great material for that.

no way. everyone knows they dont have computers in canada and he clearly would need to import all of this.

Check into your local industrial electrical warehouse (Graybar or Granger equivalents) and pick up a rack there for a couple hundred bucks. Yes internet users....you can still buy stuff locally.

Or I know that you work for a hospital, get in touch with your datacenter guys and see if they are decommissioning any old rack equipment and see if they'll let you have first dibs on it.

Are you a member of the ATL&R stance on dominance alliance recommending he construct a girlfriend out of wood instead of a server rack? :p

the elite racks are upwards of 2k at blackbox.com

id go used like others have already mentioned. if this is for a business, youre insane trying to make it out of wood.
