sorry for the late reply, and thanks for answering. The price of electricity is not a problem, we have many computers here, so we got used to the higher bills and have the budget for that and we are in Europe, not sure if there are the same strict rules about plugs as well, but if there are, the owner should look out for those rules (even if...) ...We are in an old crappy building for a few more months (hopefully not more than half a year), no built in ventilation, only the heating/cooling "radiator" that circulates hot/cold water, works pretty well actually when there are no high capacity servers in the room. Rooftop wont work in this instance, it would cost too much for now. The budget will be higher in a few months, half a year, so a proper cooling system will be set up, until then we are stuck with cheaper "temporary" solutions. We put a reflective film on the windows as a first step, will need to give it a few days of testing though, the owner of the building didnt allow the AC unit to be installed because the building will be sold soon and they didnt want to bother with the paperwork related to installing the AC even if we are the ones paying for it, so now we are running only one of the servers, the others are turned off until the new owner gets the building and we get the papers for installing additional ACs. Based on your answers only having the AC wont work? We need to ventilate the air as well? because the only option is to ventilate it through the windows, there are only tilting windows in the room, sealing that up wouldnt be fun, but we would do it if that could lower the room temps (there are not ventilation holes on the door and we cannot cut those, again because they are in the process of selling the building). Im not experienced in server room cooling, especially not in ghetto methods of cooling a server room, so thank you for any help/idea.

Hi, We are creating 3d enviroments and rendering them so we just bought more servers to speed up the rendering, put them in a small room (about 3x5 meters - 190sqft), but it gets too hot in there with the AC that this office building we are in has. We would need about 7-8kW / 25.000 BTU cooling capacity (the current setup would require about 4kW / 15-18.000 BTU, but in the future we are planning to add more servers). I saw some good AC units that is for home use mainly for about a $1000, 7-10kW, but we don't render 24/7, so i think it would handle our server room as well. What do you think? Should we somehow create airflow that moves fresh air into the room, is it necessary, or a simple AC unit is enough? (it would be pretty hard in our situation to create good airflow) Portable cooling systems are too expensive for us, around $1200 is our budget if it's possible to do it with that amount. The other thing is that on the shorter wall (3m - 10ft) are windows, 2m / 7ft tall. We were planning on putting some reflective film on the windows because the sun heats up the room, but then we have less money for the AC. Do you think it is worth it? What would you do in this situation, and in a situation where money is not a problem? Thanks!

actually the reversed KVM just popped into my head while writing, looked it up, and it looks like it would work.

Hi everybody, First post here, sorry if something the topic is in the wrong forum. I work in a 3d visualization studio, we use xeon processors, but the single threaded performance isnt quite good on those. So I want to build a PC with only the single threaded performance in mind, because many of the software we use, use only one core or one thread, but I want that PC to be accessible across the office by anyone whitin seconds (that means 4-6 people, depending what we are working on). I was reading about KVMs and that you can connect multiple PCs to a single or multiple monitors and switch between the PCs with set keyboard keys in seconds, but could not find a solution so far to the problem where you need to connect all the PCs and all the monitors to one PC and switch between your pc and the shared pc with a hotkey or a button (if there is hardware involved). reversed KVM... maybe? What are your thoughts on that, where would you start looking for a solution? Thanks! PS: Im not an IT guy
