Quirks - Graphics, PCI Slots etc
There are a few quirks to be aware of. They are not a problem if you have bought the machine to use as a server (as it is intended to be used), but they might trip you up otherwise.
On Board Graphics - The on-board graphics is at best only adequate for 2D and Windows use, and simply is not up to gaming use. Compared to even a basic i3 windows graphics are laggy and at times frustratingly slow, surfing is difficult, and at times painful with Flash enabled sites. When playing high resolution video in a window it drops frames, and the same goes for any video full screen. Low resolution video in a smaller window (e.g. YouTube) is acceptable. I find reducing the windows graphics acceleration level (putting more graphics load onto the processor) makes a small improvement. So why not replace the graphics card? Unfortunately that's not possible - see below.
PCI slots - The two standard PCI slots (cream coloured below) on the motherboard are PCI version 2.2 or 3.0, 3.3V types. To the casual observer they look as if they have been fitted the wrong way round! Older 5V PCI cards have a single slot towards the rear of the card, newer PCI cards can work at 3.3V and 5V and have slots both at the front and rear of the card. I've had an Adaptec 29160 SCSI card working perfectly in these PCI slots. See the Wikipedia page on PCI.
Graphics/PCI Express - The motherboard has 3 PCIe (PCI Express) slots (dark brown above) - one x16, one x8 and one x4. But put a graphics card in the x16 slot and the performance will not be as good as you might expect, if indeed the machine boots at all. This slot will only run at x1 speed with a graphics card fitted - my experience is (once you find a graphics card that will allow it to boot) the machine will always crash after any time up to a few hours - others also report that the machines can take a long time to POST if a graphics card is fitted. The Acer and Gigabyte sites say simply that a VGA card is not supported (it is not clear if this applies to only the x16 slot or to all three PCIe slots). This is a limitation of the Intel 3200 chipset used on the motherboard - the Intel 3200 chipset MCH datasheet (or here) under 1.2.4 PCI Express Interface states that "...The 3200/3210 MCHs do not support PCI Express graphics. The PCI Express ports are intended for external device attach."
Overclocking - Forget it. This is a server, designed for long term reliability. There is no provision in the bios for any form of overclocking, timing or voltage adjustment.
Memory (RAM) - Both ECC and non-ECC can be used, but they cannot be mixed on the board. Acer and Gigabyte claim that only ECC memory can be used, and the best ECC upgrade option I have found is from Kingston e.g. part D12872G60 (1GB) or D25672G60 (2GB). However non-ECC memory has been successfully used - the machine I bought on ebay worked fine with non-ECC DDR2 that was also a lower speed (533MHz) than standard (800MHz).
Motherboard - Made by Gigabyte, is a GA-5DXSL-RH. There were some pages on their Chinese website, but these are now gone. Gigabyte seem to deny it ever existed...
Ventilation - The CPU fan has a large plastic "trumpet" attached that goes almost (but not quite) to the vent in the side of the case. This means that if you stand the server close beside another computer (or a wall etc) then the airflow to the CPU will be restricted. Depending where you position your computers, this may be a disadvantage to you. To reduce dust ingress I have covered the side panel on my machines with filter foam, and to keep airflow to the CPU reasonable I have had to cut this trumpet down.
Processor - Relevant only if you have the E3110 Xeon - This processor is believed to be essentially identical to the Intel Core2Duo E8400 (possibly selected "best of batch" parts, and possibly with a few extra bits turned on - i.e. they are disabled in the E8400). Also, my cases have "Pentium Dual Core inside" stickers, but they definitely contain the Xeon.
Drives - Only SATA ports are provided on the motherboard, there are no IDE or SCSI ports provided, so to fit such drives you will need an add-in card (but beware of the PCI slot and drive bay issues). A SATA DVD-ROM is provided, and there is a standard floppy drive port on the motherboard. There are 6 SATA ports, so it is not possible to utilise all the drive bays without an add-in card.
Noise - All the fans in the machine are four pin speed controlled types, meaning the noise varies depending on how hot the machine gets. At turn on the fans run at full speed for a few seconds, and then rapidly slow down. The speed control is not continuously variable (smooth), but runs in a number of steps from low to maximum. When new and with only one or two hard drives fitted, these are nice quiet machines, with the fans rarely going faster than their minimum speed. Now a bit older and dustier, with several hard drives in each, they usually sit at the next fan speed up when idle - not noisy, but I know they are on now. When the fans rev at full, they are noisy machines and you do not want to be trying to work with one next to you - but this is rare, I struggle to load the processor enough to cause this to happen. I find only Norton Internet Security occasionally causes the fan speed to rise, or if a process crashes, the processor load can rise to 50% as one core is fully loaded, and then the fan speed rises to maximum.
Case Open - Being a server, if you open the case, next time you reboot the bios will complain and halt the bootup. It's not a problem, but don't open the case and then expect the machine to boot fully without going into the bios and clearing the case open status.
Windows XP - There is no official support for Windows XP. The System Setup CD will not perform a guided setup of XP, however most of the XP drivers are on the CD. Only a better version of the ethernet driver is known to be available. Some people have reported difficulties in installing XP, however it is possible that these problems are with the 64 bit version only - personally I had no problems installing XP Pro 32 bit. Hardware SATA RAID is reported by some as particular issue, some people report the Server 2003 driver can be used, but the Installation and Configuration Guide does list an XP driver (on page 52).
