Howdy, Jos! > Any recommendations? I can recommend any SuperMicro system without reservation. They use passive CPU cooling with ducted airflow and generally high quality components. You have a choice of hot-swap SATA or U320 SCSI, or the usual P-ATA stuff. They make a very "shallow" 1U rackmount as well which is 1/2 the depth of normal 1U stuff. <http://www.supermicro.com/> SuperServers start at around $425 w/o CPU, RAM, or HDD. They come with floppy, cd-rom, dual 100/1000BaseT NICs, USB, and on-board ATI graphics or Intel EXTREME chips which are well-supported by X11 DRI for 2D acceleration. You can pickup a barebone SuperMicro Server 5013G-M for about $425, plus RAM, HDD, and CPU. <http://www.asaservers.com/product.asp?pf_id=ASA%5F5013G%2DM> This supports both 400FSB and 533FSB Northwood P4s. Northwoods run really cool too. I've ordered 6 servers from ASA, they've given me excellent service. Abhi Shah done rightly by me on numerous occasions. =MB= PS: You can get them in an all black finish. -- A focus on Quality.
