Hi All, We're going to be moving into a new (to us) house in the coming months and while there's a whole heap of work for me to do, I want to ensure that I plan things out in plenty of time so most of the big decisions are well thought out. It's a traditional Victorian 3 bed terraced property with the staircase in the middle of the house, separating the lounge and dining room. There is a side-door in the dining room. Currently, it's full of the owners junk but I have plans of mounting all the networking/av/IT/etc kit in here. We will be insulating the entire floor (it's suspended) with, I think, celotex (TBC) and my initial thoughts would be to place a floor vent in front of the equipment, ideally the width of the room (the width of the staircase) to allow cool air to be in ready supply. I envisage placing all equipment in a rack (custom height) so the front of the equipment is facing the opening to the 'room' and the rear of the equipment facing the shallowest part. In terms of accessibility this will be the most ideal solution. However, in terms of adequate cooling, I'm looking forward to some advice/guidance. I am happy to construct whatever is appropriate, perhaps some box venting the width of the room, running towards the back of the rack to 'suck' all hot air up and out to a vent either into the dining room, or perhaps even across the ceiling to outside - though this would be PITA to build. In terms of kit list dreambox amp (yet to be purchased) but something like Yamaha RX-A1030 hp microserver x2 fully populated with 7200rpm disks apc ups passively cooled lounge pc (though this may change to one with fans as it may run too hot in an enclosed space which runs xbmcbuntu and perhaps Steam OS at a later date, currently onboard gpu but i suspect something on the lines of a gtx 780 24port managed switch maybe a dvd/bd player if my good lady insists I think that's about it. I haven't built anything like this in a relatively confined/enclosed space before. If there's any links to articles I have missed, it'd be great, thanks!
