I just got a WESD 51 but that is probably overkill if all you want to do is change batteries . at the very least i suggest the analogue control one WLC 100 or a WES 51 not a typo the D in my model designates it as digital control <| sep |> this is the only reasonable approach . <| sep |> For me it was the powerful vacuum cleaner . I mean , how powerful does a vacuum cleaner need to be ? For what purpose ? And also , the sum of all these things painted so complete a picture of a pianoowning , houseproud , dustaverse , stingywiththelightbulbs Little Englander I almost thought it was a parody . Yet here we are . <| sep |> I would recommend instead of a proliant server one of their z series workstations . They have hookups for gpus and are meant to be at least somewhat quiet . Any rack mount server you get , unless custom built , will not give two shits about noise levels , and it will be an uphill battle in any living space . For my htpc build I used a silverstone case that looks like a large receiver and fits an atx motherboard .
