Hi All, this is one of my Ultimate WindowsXP projects "MicroXP" , completed in 2023.

Entry
In 2023, through a fluke of luck and a trade exchange, I became the owner of a Lenovo ThinkCentre M73 Tiny. This unassuming computer, visually resembling a network terminal, cost me a set of parts to modify a Dell Precision T3500 computer. The upgrade was supposed to provide satisfactory smooth performance when emulating a PlayStation 2 on the PCSX2 emulator. What exactly did I give?
1) NVIDIA GTX960 graphics card,
2) 2 Genesis PV65 pads,
3) LGA1366 processor (INTEL XEON X5570 2.93GHz SLBF3),
If we consider that the ThinkCentre M73 kit included an external Lenovo DVD-RW burner (04X2176) with a dedicated bracket (ThinkCentre Tiny 03T9717), the price was quite a bargain.
1. What made this particular little guy the hero of the MicroXP project?
The processor, or rather its integrated graphics unit (iGPU), was the deciding factor. Looking for the smallest computer that could run Windows XP, I wanted a unit smaller than the mITX form factor—the smallest standard motherboard size for desktop computers. The answer was the Lenovo ThinkCentre M73 Tiny.
The main feature that distinguishes our star from the above-mentioned network terminals is the desktop processor socket used in it, the LGA 1150 socket, supporting 4th generation Intel processors.
The graphics chips used in this generation of processors are the last iGPUs with drivers for Windows XP.
2. Construction of the M73 Tiny:
On the front panel of the computer you will find a power switch, a USB 3.0 port, a microphone input, a headphone input, a second USB 3.0 port (yellow) – which works when the computer is turned off and can be used as a charging port, an air intake grille / internal speaker.
On the rear panel of the computer you will find a 20V power socket, a DisplayPort, two USB2.0 ports, a D-SUB (VGA) monitor output, an RJ-45 network connector, a third USB2.0 port and covered housing ports: 1. for a WIFI antenna, 2. for another device connected to the internal PCI Express/Mini Card connector.
To remove the top cover, unscrew a single screw and push the cover forward. The cover comes off without much resistance. After removing the cover, you gain access to components familiar from laptops: a 2.5-inch hard drive holder and a typical laptop CPU cooler. Beneath the removed hard drive, you'll find two slots for laptop-grade DDR3 1600MHz SODIMM memory, capable of operating in dual-channel mode.
Interestingly, the computer has an internal speaker (1.5W), just like a laptop. The model presented here has an empty PCI Express/Mini Card slot, allowing you to install, for example, a Wi-Fi/Bluetooth card and route the antenna connector to the back of the case.
3. Modifications
The M73 Tiny model featured here is equipped with a Pentium G3420T processor and 4GB of RAM in a single chip. The "T" in the processor designation indicates that it's a processor with reduced power consumption, which translates to lower temperatures but also lower performance.
To achieve maximum performance while maintaining reasonable temperatures, I decided to replace the Pentium G3240T with an i5-4590T processor. My choice was based on the same 35W TDP in both units, and the highest available HD4000 series iGPU (HD4600) integrated into the i5-4590T.

In addition to upgrading the processor to a higher model, replacing the single RAM stick with two sticks running in dual-channel mode should add a significant boost in gaming, so I replaced the 1x4GB RAM with 2x8GB. 16GB of RAM, of which only 3.5GB will be visible in Windows XP, is obviously overkill, but those are the only sticks I had, and if I successfully install a second operating system on the same drive, 16GB of RAM will provide comfortable internet browsing and office work.
The final essential component is the installed HDD – a Hitachi ‎HGST ‎Z7K500 with a capacity of 500GB. The HDD drive shows no signs of wear and tear, so it remain to serve this computer.

4. Tests
Intel's integrated HD graphics cards have always performed admirably as desktop displays. They were never known for their gaming performance, but that's not what they were designed for. Due to the type of RAM - SODIMM RAM (1600MHz), it's not the fastest DDR3 memory possible to use with the HD4600, but faster DIMM memory is in use in desktop computers.
There is no need to worry about the processor's performance, it will draw all available power from the integrated circuit, and the low TDP (despite 4 cores) should ensure temperatures at a reasonable level.
I am very curious about the performance of Intel's most powerful integrated graphics card from 2013, compared to graphics cards from the AGP connector era.
The use include benchmarks from 3Dmark and Unigine, as well as benchmarks built into games => tests that allow to compare results on different computers.
In the last column, I've listed the performance gains in each test. The results show the change after replacing only the processor. Other components, drivers, and software settings remain the same.
I treat the performance drop (-2%) in the Painkiller c5l2 test as an exception at work, the game runs smoother, but the benchmark does not see any improvement compared to the weaker processor.
After purchasing and running the first tests, temperatures spiked to over 80 degrees Celsius. The thermal paste on the processor was bone dry :p After changing the thermal paste, the highest temperatures I observed in benchmarks reached 68 degrees Celsius. In games, it reached around 55 degrees Celsius.
Drivers
All tests were performed with driver version 6.14.10.5449 installed. I noticed significant errors when testing Far Cry and Crysis. Strangely, Far Cry 2 didn't show these types of errors.

IMPORTANT NOTICE!
Intel drivers do not support HDMI/DisplayPort output for the Haswell GT2 chip (HD4600 in this case).
After replacing the processor, turning on the computer, and installing the drivers, the only result after restarting is a black screen. I've tested all the drivers available online.
The drivers support the VGA connector without any problems – In this particular case, the image provided by the adapter
(VGA -> HDMI + mini-jack + USB power), the highest possible screen resolution to choose from is 1680×1050 pixels.

Summary:
The Lenovo ThinkCentre M73 Tiny's "MicroXP" project is the smallest full-featured computer with native Windows XP support. Can it be called "Gaming Computer" for Windows XP games? I dont know. I will know when I will come back into retro gaming buisness :p, and I will be able to compare benchmark`s results with another retro computers.
We have a microcomputer that can handle games at 1280x1024 pixels, with a DVD drive (we can install original games), and with EAX support when connected to an external sound card. Generally, games run satisfactorily at this resolution; NFS: Most Wanted runs surprisingly well (averaging over 40k/s), and even Far Cry, Far Cry 2, and Crysis run decently, but texture errors (shaders) ruin the experience, and there's no guarantee that such significant distortions won't occur in other titles.

I had same PC, but for my taste very noise, I sold

Finally i buy a fanless industrial miniPC with i5-2520m, 16GB and SSD

Very cute!

I think my favourite small PC form factors was the Shuttle. Nowhere near as compact as this of course, but they support full size Graphics and Soundcards and also full size optical, HDD and floppy. My favourite one died. That had Athlon XP 3200+ (Barton Core) and Ati 9700 pro. Was a fantastic early XP machine. Probably could have put Win98 on it, but I never tried.

You can actually get the RAM fully usable in Windows XP.

Maybe some (Older) Drivers are not PAE aware, in that Case grab Windows Server 2003 Drivers instead.

File with scores in .png format is unreadable and I dont see edit option, so I`m uploading my benchmarks scores list in .pdf format.
