This is how the system looks completed as of 29/07/2015 Hi all. I'm somewhat new to the site and have decided to take the plunge and join the forums to share with you my love of all things computer related. I'm am in the process of building my ideal Pentium 4 (socket 478) for my older games/software and as something I can put away for a few years and bring out the loft to show my two kids what I feel was a really cool stage in the desktop PC's evolution. So a bit of history before we move on to a few pictures. I brought the system from a lad in Cambridge for the sum of £20 as I buy/sell/repair PC's on my own since both me and my other half lost our jobs in the industry do to the company outsourcing. When I got home I took a good look at the PC and realised there could be some potential to build a really hot little system out of something that when new was a pile of rubbish. The system in question is a HP D230MT a basic little micro tower that was made back in 2005 and retailed here for about £250 new. I wanted too see just how 'modern' I could make the system and see if the old 478 architecture had any real life left in it. A friend of mine called me crazy as he firmly believes that anything more then 4-5 years old is old and no use and he gave me a little challenge and that was too see how far I could upgrade the system and see if an old HP desktop running a 478 chip could still be used today with any form of speed. The only thing was I could not change the case or the motherboard but everything else was subject to change. So like some sort of wanna-be superhero I flew to the keyboard and just missed stepping on the cat to jump on old eBay and source some parts. Now the original specs were: 2.4Ghz Pentium 4 with a 400Mhz FSB 256MB of DDR333 40GB Hard drive of some nature (OEM stickers covered up the brand) Onboard video (about 16MB of shared *shudders*) DVD-ROM drive that had packed in and last of all some cheapo 250w PSU I purchased the following parts: 3.06Ghz Pentium 4 (0.13m) 2GB of Crucial DDR400 250GB Seagate IDE hard drive with a 7000.3RPM rated speed and finally a nice ATI HD3650 with 1GB of dedicated GDDR2 memory After a lot of messing about and tweaking the hell out of the O/S the system ran everything thrown at it like a beast but after a few days of playing around I got bored. I really wanted a Pentium 4 Prescott core, the EE edition would be lovely but they command high prices online so I thought I would just leave it until I get a call. Someone I knew through a friend was giving away his collection of old systems and asked me if I wanted them, of course I said yes. Little did I know one of them would have a Gigabyte GA-8IG1000MK! This was great news as I could now think about at least upgrading to a 90nm CPU but I was in for one more shock. While lifting the heatsink and rubbing off the old compound with a lint free cloth I nearly wet myself! There was staring me in the face a Pentium 4 EE!! 3.4Ghz of overheating goodness! So out with the old HP motherboard and after a bit of refurbishment and a good deep clean the system was built with a lot of new parts and is sat on my desk burring away waiting for me to get back on with playing some old GTA3 The system now stands in the HP case (but not for long) with the following: 3.4Ghz Intel Pentium 4 HT EE with a 800Mhz FSB and 1MB of level2 cache. 3GB of DDR400 memory from Crucial 500W Liteon PSU The ATI HD3650 and 250GB Seagate HDD Now though I want to over clock the system and sort out thermals so I will be asking for a little advice a bit later One final thing, the front of the system is black and should be silver but I hated the silver and went looking for a fascia from a D220MT as that was black. it took me 4-5 months of hard looking but i finally found one in the U.S and had it shipped over to the UK.
